[37] | 1 | function y = scale_cols(x, s) |
2 | % SCALE_COLS Scale each column of a matrix. | |
3 | % SCALE_COLS(x,s) returns matrix y, same size as x, such that | |
4 | % y(:,i) = x(:,i)*s(i) | |
5 | % It is more efficient than x*diag(s). | |
6 | ||
7 | y = x.*repmat(s(:)', rows(x), 1); | |
8 | %y = x.*(ones(rows(x),1)*s(:)'); |
