Taking a mean of a fixed length number of points

[Henk Borsje]

This question is not of crucial importance, but I’m curious if there is a better alternative.

 

I need to calculate the columnar average of each k points out of an array of x(n,m) elements, resulting in a new array  x_avg (floor (n/k) , m) elements.

 

I use:

 

        tmp = reshape(x,k,[],m);                                      (1)

        x_avg = reshape(mean(tmp),[],m);                  (2)

 

I wonder if there is a simpler or more direct way, except for substituting equation (1) into (2)
