MATLAB: How to subtract Mean from Matrix along columns

Question

Hi,

In subtraction, there is an example of subtract mean from matrix: A – mean(A) and it works well. But I have a matrix A of 15X1000, and I want to subtract the mean mean(A, 2) along the 1000 columns, how to do that? Thanks Jennifer

Answer 1

With the above help, found that bsxfun works for versions before 2017a:

bsxfun(@minus, A, mean(A, 2))
