MATLAB: I want to divide each row of a matrix with corresponding element in another matrix .Please help.

Question

For eg: I have a matrix

 A=[9 6 3;          
    4 2 8;
    1 0 0;]

divide A by B=[3 2 1] to get the result

C=[3 2 1;
   2 1 4;
   1 0 0;]

Answer 1

Use bsxfun:

>> A = [9,6,3;4,2,8;1,0,0];
>> B = [3,2,1];
>> bsxfun(@rdivide,A,B(:))
ans =
     3     2     1
     2     1     4
     1     0     0
