Mean of some elements in a matrix

I have a matrix A of dimension 25 x 51. I want to calculate the mean of every sequential 5 elements of each row and store them in another matrix. Precisely I want to compute mean(A(1:5,1)), mean(A(6:10,1)) and so on for all columns and save it in another matrix Q of dimension 5 x 51.

Can anyone help me out with the loop??

Using SEPBLOCKFUN ( Download ),

 result=sepblockfun(yourMatrix,[5,1],'mean');
