in [Matlab]

From: Hermano Cappa on 30 Mar 2010 07:48 Hi, I want to write a easy method for a simple matrix operation but I don't know how to start. I have two matrices A and B: A = [0 0.5; 1 1.5; 2 2.5]; % number of rows can change, columns is 2 B = [10; 20]; % 2 x 1 matrix I want combine them to a matrix C with the result: C = [0 10; 0.5 20; 1 10; 1.5 20; 2 10; 2.5 20]; How can I do this? Thanks
