For any matrix A, how would I subtract the row means from each row, so that each row has a mean of zero?

The row means would be calculated as the mean of dimension 2.
Try this:
A = rand(5);
Anew = A - mean(A,2);
Check = mean(Anew,2) % Confirm: Mean = 0

sorry for activating this old thread but proved quite useful.
If I need to do a column means for the same problem statement, how would I do that. One way is to do a transpose of the matrix. I couldn't find anything in the documentataion.

No worries!
To do column means, use mean without any extra arguments (it defaults to taking the column means), or specifying 1 as the dimension (instead of 2).
