Matlab errors: Subscript Indices must either be real positive integers or Logicals.Subscript index must be of positive integer type or logical type

Cause of error: in the process of accessing the matrix (including vector, two-dimensional matrix, multidimensional array, same below), the index of the subscript either starts at 0 or has a negative number. Note: The syntax of MATLAB stipulates that the index of the matrix starts from 1, which is different from the habit of programming languages such as C.

Solution: Debug the program yourself and fix subscripts that are zero or negative.

I made a mistake when I was writing the program. I should have done the transpose of the matrix, but I forgot…
