Matlab code help (simple)

Hi,

I am working on a project on matlab and after doing some processes I created a new matrix like;

A=[0 0 0; 0 0 0; 1 3 2; 0 0 0; 0 0 0; 4 8 3; ....... ] ( size of A is mxn for example)

As a result there are some datas in every 3th row. Now I want to take them and put to another matrix in order like [1 3 2; 4 8 3] ... I tried to that with some for loops but it didn't result well. Does anyone know how to write that?

Thanks...

Why didn't it work?
Post your loop code
