suppose your matrix is called "X". if you want to scale each row by a known factor, write this code:

% define a column vector called S where S(i) is the scaling factor for each row.
[~,c] = size(X)
Xp = repmat(S,[1 c]).*X % the scaled matrix

vector S must have the same number of rows as matrix X. the values in S must be around 1 (eg: 0.92, 1.04,etc) to not change your main matrix entirely but that's on your own.
