how to substract respective columns of 2 matrices in matlab

To subtract the respective columns of two matrices, the matrices must have the same number of columns. You can use the minus function in MATLAB to subtract the two matrices. Here's an example code:

main.m
A = [1 2 3; 4 5 6; 7 8 9];
B = [9 8 7; 6 5 4; 3 2 1];

C = A - B;

In this example, matrix A and matrix B have the same dimensions (3x3). The minus function is used to subtract the corresponding elements of each matrix. The resulting matrix C will also be a 3x3 matrix where each element is the difference of the corresponding elements of A and B.
