Method one:
findpeaks function
PKS = findpeaks(data)
[PKS,locs] = findpeaks(data) — the number of peaks corresponding to PKS and locs
[…] = findpeaks(data,’minpeakheight’, MPH)– MPH sets the minimum peakheight
[…] = findpeaks(data,’minpeakdistance’, MPD)– MPD sets the minimum interval between two peaks
[…] = findpeaks(data,’threshold’,th)
[…] = findpeaks(data,’npeaks’,np)
[…] = findpeaks(data,’sortstr’, STR)
the command findpeaks is used to findpeaks of a vector that is greater than the value of two adjacent elements.
for example:
a=[1 3 2 5 6 8 5 3];
findpeaks(a),
returns 3 8
[v,l]= findbb2 (a),
returns
v=3 8
l=2 6
if a is a matrix, the values and locations of the peaks are listed in column search order.
For more information, see Help FindPeaks
Disadvantages:
You can only find the peak, you can’t find the trough.

Method 2:
IndMin=find(diff(sign(diff(data)))> 0) + 1;
IndMax=find(diff(sign(diff(data)))< 0) + 1;
where,
IndMin, data(IndMin) corresponds to the trough data
IndMax,data(IndMax) corresponds to the crest data
>> a=[1 3 2 5 6 8 5 3]
a =
1 3 2 5 6 8 5 3
>> IndMax=find(diff(sign(diff(a)))<0)+1
IndMax =
2 6
>> a(IndMax)
ans =
3 8
>> IndMin=find(diff(sign(diff(a)))>0)+1
IndMin =

http://www.mkyong.com/hibernate/how-to-call-store-procedure-in-hibernate/
In this tutorial, you will learn how to call a store procedure in Hibernate.
MySQL store procedure
Here’s a MySQL store procedure, which accept a stock code parameter and return the related stock data.
SQL
DELIMITER $$
CREATE PROCEDURE `GetStocks`(int_stockcode varchar(20))
BEGIN
SELECT * FROM stock where stock_code = int_stockcode;
END $$
DELIMITER ;
In MySQL, you can simple call it with a call keyword :
SQL
CALL GetStocks('7277');
Hibernate call store procedure
In Hibernate, there are three approaches to call a database store procedure.
1. Native SQL – createSQLQuery
You can use createSQLQuery() to call a store procedure directly.
Java
Query query = session.createSQLQuery(
"CALL GetStocks(:stockCode)")
.addEntity(Stock.class)
.setParameter("stockCode", "7277");
List result = query.list();
for(int i=0; i<result.size(); i++){
Stock stock = (Stock)result.get(i);
System.out.println(stock.getStockCode());
}
2. NamedNativeQuery in annotation
Declare your store procedure inside the @NamedNativeQueries annotation.
Java
//Stock.java
...
@NamedNativeQueries({
@NamedNativeQuery(
name = "callStockStoreProcedure",
query = "CALL GetStocks(:stockCode)",
resultClass = Stock.class
)
})
@Entity
@Table(name = "stock")
public class Stock implements java.io.Serializable {
...
Call it with getNamedQuery().
Java
Query query = session.getNamedQuery("callStockStoreProcedure")
.setParameter("stockCode", "7277");
List result = query.list();
for(int i=0; i<result.size(); i++){
Stock stock = (Stock)result.get(i);
System.out.println(stock.getStockCode());
}
3. sql-query in XML mapping file
Declare your store procedure inside the “sql-query” tag.
Markup
<!-- Stock.hbm.xml -->
...
<hibernate-mapping>
<class name="com.mkyong.common.Stock" table="stock" ...>
<id name="stockId" type="java.lang.Integer">
<column name="STOCK_ID" />
<generator class="identity" />
</id>
<property name="stockCode" type="string">
<column name="STOCK_CODE" length="10" not-null="true" unique="true" />
</property>
...
</class>
<sql-query name="callStockStoreProcedure">
<return alias="stock" class="com.mkyong.common.Stock"/>
<![CDATA[CALL GetStocks(:stockCode)]]>
</sql-query>
</hibernate-mapping>
Call it with getNamedQuery().
Java
Query query = session.getNamedQuery("callStockStoreProcedure")
.setParameter("stockCode", "7277");
List result = query.list();
for(int i=0; i<result.size(); i++){
Stock stock = (Stock)result.get(i);
System.out.println(stock.getStockCode());
}
Conclusion
The above three approaches are doing the same thing, call a store procedure in database. There are not much big different between the three approaches, which method you choose is depend on your personal prefer.
【 Problem Description 】
Reverse digits of an integer.
Example1: x = 123, return 321
Example2: x = -123, return -321
click to show spoilers.
[thinking]
This problem seems simple, but there are more pits.
Integer inversion is a simple problem, but overflow needs to be dealt with.
Save the result as a long, returning 0 if it is greater than the integer maximum or less than the negative minimum
[code]
public class Solution {
public int reverse(int x) {
if (x == 0) {
return 0;
}
int sign = 1;
if (x < 0) {
sign = -1;
}
long result = 0;
long t = Math.abs((long) x);
while (t != 0) {
result = result * 10 + t % 10;
;
t /= 10;
}
if ((sign == 1 && result > Integer.MAX_VALUE)
|| (sign == -1 && sign * result < Integer.MIN_VALUE)) {
return 0;
}
return sign * (int) result;
}

A detailed description of the BLOB download problem
I want to use the SRC url blob:https%3A//www.youtube.com/23aea5c8-9ae2-40dc-9417-e675ea99b386 download video, but I don't know how to do it.
Is there a general way to download this kind of video?
Recommended solutions
I found a way to download a video using the blob url in Vimeo (I didn't know how until I read this article). I'm using Google Chrome. Here are the steps:
open More Tools> Developer Tools check if there is something like this in the video tag:
<video preload="" src="blob:https://player.vimeo.com/XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX"></video>
Copy the iframe SRC (if any) value of the label, such as http://player.vimeo.com/video/XYZ , if you find that it can be replicated, jump straight to point 7, otherwise in accordance with the step 4 and 6 to continue operating. Now find the string in the page https://skyfire.vimeocdn.com/... /master.json?Base64_init =1(using the Developer View), it should be found in the javascript function, like this:
(function(e,a){var t={"cdn_url":"https://f.vimeocdn.com","view":1,"request":{"files":{"dash":{"origin":"gcs","url":"https://48skyfiregce-a.akamaihd.net/.../master.json?base64_init=1","cdn":"
Force a.akamaihd.net/... copy the link from the url field above to a new Chrome TAB, such as https://48skyfiregce-a.akamaihd.net/... /master.json?Base64_init =1, then open it with a browser, it will open a json file like this:
{
"clip_id": XYZ,
"base_url": "../",
"video": [
{ ... ... ...
Use id now XYZ combination structure a URL, as shown in the following: https://player.vimeo.com/video/XYZ are replaced with the final URL video tag within the blob:https://player.vimeo.com/XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX (created in the previous step # 6). Now you can see that, magically, the SRC field inside the video tag has changed (if not, try Step 7 multiple times)...
<video preload="none" src="https://fpdl.vimeocdn.com/vimeo-prod-skyfire-std-us/XX/XXX/X/XXXXXXXX/XXXXXXXXX.mp4?token=abcdefg"></video>
Finally, using the new link to download it directly, like this: https://fpdl.vimeocdn.com/vimeo-prod-skyfire-std-us/XX/XXX/X/XXXXXXXX/XXXXXXXXX.mp4?token=abcdefg
Other solutions
The answer is for the Twitter url -
right click on the video, then click check element -
You'll find code like this

From the JSON format above, you can see the value of video_URL
https://video.twimg.com/ext_tw_video/844504104512749568/pu/pl/e91Du5N2TZ09ZaW_.m3u8
The problem here is that after August 1, 2016, Twitter stopped using.MP4 video and instead converted to a new HLS, adaptive streaming format with a.m3u8 file extension.
The.m3u8 files are basically just a wrapper around the text, and they are very small (300-500 bytes). When you open them with a text editor, they contain links to different video sizes
in Notepad++ (Notepad++) open the file m3u8, which will contain the code
EXTM3U EXT-X-INDEPENDENT-SEGMENTS EXT - X - STREAM - INF: PROGRAM - ID = 1, BANDWIDTH = 256000, RESOLUTION = 180 x320 CODECS = "mp4a. 40.2, avc1.42001 f"/ext_tw_video/844504104512749568/pu/pl/180 x320/_Z42SY5zwMlLdFYx m3u8 EXT - X - STREAM - INF: PROGRAM - ID = 1, BANDW IDTH = 832000, 360 x640 RESOLUTION =, CODECS = "mp4a. 40.2, avc1.42001 f"/ext_tw_video/844504104512749568/pu/pl/360 x640/- Phfjbbx2yinirLi. M3u8
copy the corresponding link from above according to the resolution you need. Repeat the same steps until you have a.ts file. Download the.TS file (video file).

When writing Unity Shader, there are times when you need to write shader that can support Unity’s built-in Lightmap or Light probe. If you’re writing with Surface, you don’t have to worry about that. Unity will compile automatically, but if you’re writing with Vert& Frag writes shader, these need to add their own code to call.
Unity has a built-in lightMap call
To make the unity built-in data and various macro definitions (such as LIGHTMAP_OFF in this article) work, you need to add #pragma:
pragma multi_compile LIGHTMAP_OFF LIGHTMAP_ON
Prior to Unity5.0, there were two built-in parameters that needed to be declared. With Unity5.0, they were not required:
half4 unity_LightmapST;
sampler2D unity_Lightmap;
Lightmap is a UV2 that USES the model, so next declare uV2 in the vertex input structure:
float2 texcoord1 : TEXCOORD1;
In another vertex structure, define the UV value used to receive UV2:
ifndef LIGHTMAP_OFF
half2 uvLM : TEXCOORD4;
endif
Assign uvLM to the vert function:
ifndef LIGHTMAP_OFF
o.uvLM = v.texcoord1.xy * unity_LightmapST.xy + unity_LightmapST.zw;
endif
Then the frag function samples the lightMap map and adds it to the main color:
ifndef LIGHTMAP_OFF
fixed3 lm = DecodeLightmap (UNITY_SAMPLE_TEX2D(unity_Lightmap, i.uvLM.xy));
col.rgb*=lm;
endif
In the above code, DecodeLightmap is used to decode unity’s built-in LightMap. This is because the LightMap baked by unity is a 32-bit HDR map. On the desktop side, the code of the LightMap is RGBM, while on the mobile side, in most cases, the code of the LightMap is double-ldr, so different coding methods should be provided for different platforms. DecodeLightmap is here, it can decode the light map for different platforms

ENDCG

}
}
A call of Unity’s built-in Light Probes
In shader we call Light Probes using Half3 ShadeSH9(Half4 Normal) defined by Unity. Light Probes lighting USES a simulation called Sphere Harmonic, or SH, so in ShadeSH9 the normal in a world coordinate is needed to determine the Light on the surface of the object.
First we define a parameter SHLighting in the vertex output structure:
fixed3 SHLighting : COLOR;
Then assign it to a vertex function:
float3 worldNormal = mul((float3x3)_Object2World, v.normal); Get normal in world coordinates
o.SHLighting= ShadeSH9(float4(worldNormal,1)) ;
VF version code 02:

The questions in the original
Reverse digits of an integer.
Example1: x = 123, return 321
Example2: x = -123, return -321
The title translation
Reverses the number in an integer.
example 1: given x=123, return 321; Example 2: Given x=-123, return -321.
If x is equal to 10 or x is equal to 100, then both returns 1. 2. What happens to overflow after the original integer is reversed?– For example, if x=1000000003, reverse overflow, then the specified overflow results will return 0.
Thinking method
Here, Python’s handling of integers doesn’t actively overflow and actually causes problems, requiring special handling.
Thinking a
Loop through the modulus of 10 to get the tail number, step by step multiply 10 to construct a new flipped integer. However, it is important to first judge the positive and negative of the original number, and finally judge whether the result is overflow.
code
class Solution(object):
def reverse(self, x):
"""
:type x: int
:rtype: int
"""
flag = 1 if x >= 0 else -1
new_x, x = 0, abs(x)
while x:
new_x = 10 * new_x + x % 10
x /= 10
new_x = flag * new_x
return new_x if new_x < 2147483648 and new_x >= -2147483648 else 0

Python string reversal is used to reverse an integer, and the reversed string is converted back to an integer. As above, pay attention to positive and negative and overflow situations.
code
class Solution(object):
def reverse(self, x):
"""
:type x: int
:rtype: int
"""
x = int(str(x)[::-1]) if x >= 0 else - int(str(-x)[::-1])
return x if x < 2147483648 and x >= -2147483648 else 0
