Matlab Error Message?

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 1x6, x2 is 100x6?

Does anyone know where is the problem?

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.

That is fine Thank you

Maybe you're after this: (????)

Cr = rand(1,6);
x2 = rand(100,6);
x = zeros(100, 6); % Preallocate
for row = 1 : size(x2, 1)
  x(row, :) = Cr(1:end) .* x2(row,:);
end
x
