Add a new page in latex
When we use Latex, we sometimes need to start a new page to continue writing. Instead of using \ newPage, you’d better implement this using \ ClearPage.
Because:
\newpage: The \newpage command ends The current page.
\clearpage: The \clearpage command ends the current page and causes all figures and tables that have so far appeared in the input to be printed.
In plain English, when you add a large number of new pages, the two are basically the same. When you add a small number of new pages, \ NewPage won’t achieve the effect you want, but \ ClearPage will.
Here’s an example:
Exp1:
\documentclass[twocolumn]{article}
\usepackage{CJK}
\setlength\textwidth{8cm}
\setlength\textheight{8cm}
\begin{document}
\begin{CJK*}{song}
\CJKtilde
first side
\newpage
sorry, first side
\clearpage
\end{CJK*}
\end{document}
Exp2:
\documentclass[twocolumn]{article}
\usepackage{CJK}
\setlength\textwidth{8cm}
\setlength\textheight{8cm}
\begin{document}
\begin{CJK*}{song}
\CJKtilde
first side
\clearpage
haha, second side
\clearpage
\end{CJK*}
\end{document}

Incomplete and “the Jupiter” distribution was not found
After using PIP Uninstall or Conda Uninstall jupyter, it is common to find that a jupyter notebook has not been fully uninstalled because PIP uninstalls only some of its packages when it is uninstalled.
Complete unloading of jupyter can be used:
Complete unloading of jupyter can be used:
pip install pip-autoremove
pip-auto remove jupyter -yCan delete complete jupyter
It actually deletes the following related libraries, and if there are libraries that other libraries depend on, you can manually uninstall those that are not needed.
pip uninstall jupyter
pip uninstall jupyter_core
pip uninstall jupyter-client
pip uninstall jupyter-console
pip uninstall notebook
pip uninstall qtconsole
pip uninstall nbconvert
pip uninstall nbformatPay attention to the PIP/PIP3 switch.
“The jupyter” distribution was not found, but on The command line type jupyter still exists, because there are several jupyter computers in The system. This problem seems to be relatively rare, and there are few discussions on CSDN /stack Overflow. I happened to encounter this error today and solved it, so I would like to share the solution here.
The crux of the matter is that it is possible to have multiple versions of jupyters installed in multiple Python/PIP environments, and when PIP Uninstall, only jupyters for this version are uninstalled. The version using piPs can be viewed with which PIP, and you can use which -a PIP to view all piPs installed on your machine.
Therefore, we can see all versions of jupyter with which -a jupyter and then corresponding to one by one uninstall. For the most part, the file paths for jupyter and PIP are the same, so it is enough to remove them with the PIP of that directory.
such as, suppose we see a jupyter path is /usr/local/bin/jupyter, we can use the following command to remove it:
/usr/local/bin/pip uninstall jupyterOf course you can ls the directory to see all jupyter related libraries, and then use the top of the manual unload way to remove one by one.
Of course it is possible that you have something like jupyter under Snap, if you see a jupyter that is something like /usr/bin/Snap under the directory.
for jupyter, snap remove jupyter can be uninstalled using snap remove jupyter.
Remove all versions of jupyter and a jupyter notebook and then use PIP Install to reinstall, with PIP Install-U PIP of course recommended to update the PIP before installation
Finally, the possible cause of this error is personal analysis under anaconda environment when installing jupyter, using Sudo APT install jupyter-core or Sudo Snap install jupyter. Use conda Install or PIP Install jupyter as far as possible for a jupyter installation.

Vector series in actual C + +_ To_ fit()
Vector has been almost written, and it seems to be nearing the end. Everything from initialization to how to add elements to copy element has been involved, so it is time to talk about the memory release.
Yes, for the vector with a small amount of data, it is completely unnecessary to actively release it by itself, because it will have little impact on the efficiency of the program. However, when a large amount of data is stored in the vector and some operations are carried out on the data, such as deletion, it is very wise if we can actively release the memory.
So if We write here, it should make the difference between size and capacity clear.
Now introduce one method, STD: : vector: : clear ()
Removes all elements from the vector (which are destroyed), brigade the container with a size of 0.
see clear, mentioned in the English language is size = 0, rather than capacity. Write programs to verify some:
#include<iostream>
#include<vector>
using namespace std;
int main()
{
vector<int> v;
v.push_back(1);
v.push_back(2);
v.push_back(3);
v.push_back(4);
v.push_back(5);
cout << "size:" << v.size() << endl;
cout << "capacity:" << v.capacity() << endl;
v.clear();
cout << "after clear size:" << v.size() << endl;
cout << "after clear capacity:" << v.capacity() << endl;
return 0;
}
//Output
size:5
capacity:6
after clear size:0
after clear capacity:6See, after clearing, the size changes to 0 and the capacity remains the same. Read the description of clear in English again.
A reallocation is not guaranteed to happen, and the vector capacity is not guaranteed to change due to calling this function. A typical alternative that forces a reallocation is to use swap:
vector().swap(x); // clear x reallocating
std::vector::swap
Exchanges the content of the container by the content of x, which is another vector object of the same type. Sizes may differ.
After the call to this member function, the elements in this container are those which were in x before the call, and the elements of x are those which were in this. All iterators, references and pointers remain valid for the swapped objects.
Notice that a non-member function exists with the same name, swap, overloading that algorithm with an optimization that behaves like this member function.
A direct look at the use of.
#include <iostream>
#include <vector>
int main()
{
std::vector<int> foo;
foo.push_back(1);
foo.push_back(2);
foo.push_back(3);
foo.push_back(4);
foo.push_back(5);
std::vector<int> bar;
bar.push_back(1);
bar.push_back(2);
std::cout << "foo size:" << foo.size() << std::endl;
std::cout << "foo capacity:" << foo.capacity() << std::endl;
std::cout << "bar size:" << bar.size() << std::endl;
std::cout << "bar capacity:" << bar.capacity() << std::endl;
foo.swap(bar);
std::cout << "after swap foo size:" << foo.size() << std::endl;
std::cout << "after swap foo capacity:" << foo.capacity() << std::endl;
std::cout << "after swap bar size:" << bar.size() << std::endl;
std::cout << "after swap bar capacity:" << bar.capacity() << std::endl;
return 0;
}
//Output：
foo size:5
foo capacity:6
bar size:2
bar capacity:2
after swap foo size:2
after swap foo capacity:2
after swap bar size:5
after swap bar capacity:6See, after swap, not only the size has changed, but the capacity has also changed. So swap replace clear:
#include<iostream>
#include<vector>
using namespace std;
int main()
{
vector<int> v;
v.push_back(1);
v.push_back(2);
v.push_back(3);
v.push_back(4);
v.push_back(5);
cout << "size:" << v.size() << endl;
cout << "capacity:" << v.capacity() << endl;
vector<int>().swap(v);
cout << "after swap size:" << v.size() << endl;
cout << "after swap capacity:" << v.capacity() << endl;
return 0;
}
//output：
size:5
capacity:6
after swap size:0
after swap capacity:0Remember that shrink_to_fit() on the previous blog is called Shrink_to_fit (), and if clear then calls Shrink_to_fit (), then that doesn’t work?
#include<iostream>
#include<vector>
using namespace std;
int main()
{
vector<int> v;
v.push_back(1);
v.push_back(2);
v.push_back(3);
v.push_back(4);
v.push_back(5);
cout << "size:" << v.size() << endl;
cout << "capacity:" << v.capacity() << endl;
v.clear();
v.shrink_to_fit();
cout << "after swap size:" << v.size() << endl;
cout << "after swap capacity:" << v.capacity() << endl;
return 0;
}
//output：
size:5
capacity:6
after swap size:0
after swap capacity:0Instead of assuming that swap replaces clear can release the vector’s memory correctly, C++11 launches the shrink_to_fit method, and then does the same.

The difference of four kinds of integer function (fix floor ceil round) in MATLAB
There are four integral functions in Matlab: Fix, floor, Ceil and Round. The specific application methods are as follows:
(1) fix
is rounded in the direction of zero
Such as
Fix (1.3) = 1
Fix (1.3) = 1;
(2) floor
is rounded in the direction of minus infinity (the maximum integer not exceeding x. (gaussian is rounded))
Such as
Floor (1.3) = 2
Floor (1.3) = 1;
(3) ceil
is rounded in the direction of positive infinity (the smallest integer greater than x)
Such as
The ceil (1.3) = 1
The ceil (1.3) = 2;
(4) round
rounded to the nearest integer
Such as
Round (1.3) = 1
Round (1.52) = 2
Round (1.3) = 1
Round (1.52) = 2

From there you can change the view Settings, as the Menu bar is hidden in Scale view. From there you can change the view Settings because the Menu bar is hidden in the Scale view.

The other solution (poor one) is to exit the VM Box and save the desktop (top option), and reboot to bring back the screen just as before rezooming.
Remove M Characters “Control M” or “^M” or “CTRL M” Characters in a UNIX file
ubuntu:
sudo apt-get install dos2unix
dos2unix file
sudo apt-get install dos2unix
dos2unix file
ohh do you want to remove M characters in UNIX ?Though i am not so good in UNIX but this time i had to get my hand dirty in UNIX.
Reasons were, there is no one to support things from UNIX perspective. And all of sudden I got 20+ UNIX scripts to work upon. You can imagine that what would have happened to me. I am in one among them who does not even like to see that raw black screen. It is a bizarre for me!!!!! This happens when you import files from MS-DOS to UNIX system and is a very common issue,
Objective of this post is to address below questions
- Why I am seeing ^M (control M ) character in UNIX file ? How to make my UNIX script \ file clean and without ^M (control M) character?What’s the best method to remove M characters or ( ^M ) from any UNIX file ?
You can do it by two ways. Script or manual, and my vote will be for Script as it has only one step as opposite to manual method where we need to perform two steps. Moreover it helps you to be calm when everyone in a team is spoiling files on which you are supposed to work !!!!!!!.
Remove M Characters (^M) with Unix commands
Using dos2unix command
dos2unix ORIG_FILENAME TEMP_FILENAME
mv TEMP_FILENAME ORIG_FILENAME
IMP NOTE:
use dos2ux command if you are using HPUX
Using sed command
sed ‘s/^M//g’ ORIG_FILENAME > TEMP_FILENAME
mv
TEMP_FILENAME
ORIG_FILENAME
IMP NOTE: To get ^M in UNIX (Hold control key and then press v and m character).
Using vi Editor
ESCAPE :%s/^M//g ENTER
IMP NOTE: To get ^M in UNIX (Hold control key and then press v and m character).
Remove M Characters (^M) with Unix Script
You can put above command in UNIX and it will do wonder as now you just have to give one parameter to that script. A script code is below and looks at the picture to understand that how it works.
#!/bin/sh
TEMPORARY _FILE=”/TEMP_FOLDER/$$”
if [ $# -ne 1 ] ; then
echo “USAGE $0 Provide-Dos-File-Name”
exit 4
fi
dos2unix $1 > $TEMPORARY_FILE && mv $TEMPORARY_FILE $1

### Enable below for HPUX

Unix Script for Removing CTRL M Character – Screen Shot
To Remove m Characters:
Step 1 : save script as w2x
Step 2: if you are in same directory call script as w2x FileName_To beConverted
Step 3: Confirm that file doesn’t have ^M character in it now by opening it in vi editor. Important that these characters are only visible in Vi can can’t be seen through more or cat.
To call it from anywhere: you need to make small entry in .profile or .login or .cshrc file which is generally hidden and can’t be seen simply. you can use (ls -a) to see hidden files.
Request you to share through comments if you are aware of any other method to remove M characters (^M) in UNIX.
Thanks
