Hi, Please excuse total n00b here.

I am after devision of matrix by a second matrix, example;

x = [4; 8; 12; 16; 20];

y = [2 4];

I want x/y to give

ans = [2 1; 4 2; 6 3; 8 4; 10 5]

Thanks

The bsxfun() command will automatically replicate arrays across the dimensions you need:

bsxfun(@rdivide,x,y)

I recommend reading "doc bsxfun" to get an understanding of the function.

Thanks for the quick response. It was just what the doctor ordered. Yes I threw it straight at the help file to get more of an explanation.

Thanks again.
