MATLAB: Is there any way of doing this operation without a loop

Question

I want to do following operarion between an array (A) and a vector (B):

A(i,j)/B(i)

Is there any way to do it without looping? rdivide requires both A and B to be the same size…

Thank you!

Answer 1

Use bsxfun. Note that the non-singleton dimensions have to be the same, so you may have to transpose your matrix, but the result should be the same.

Example:

A = randi(10, 5, 4);
B = randi(20, 5, 1);
C = bsxfun(@rdivide, A, B);
