MATLAB: Matlab Error Message

Question

I have the below matlab code, and I got this error "Subscripted assignment dimension mismatch"

   for s=1:6
    x(:,s) = Cr(1,s) .* x2(:,s);
   end

Cr is 1×6, x2 is 100×6?

Does anyone know where is the problem?

Answer 1

Your x must have strictly more or less than 100 rows. Hence the assignment fails.

Note that a much simpler way of achieving what you want is with bsxfun:

x = bsxfun(@times, Cr, x2)  %that's all that's needed. No loop.
