So I have a matrix of the size 23x15 and a column vector of size 23x1. I need to subtract element 1 of the colum vector from the 1st row of the matrix, element 2 of the column vector from 2nd row of the matrix, and so on. Any suggestions about how I can do it?

Hi. If the matrix and the vector have compatible size (= like you mentioned), it is enough to use the minus operator:
A = rand(23,15);
x = rand(23,1);
A-x
