How to apply the mean function on multidimenssional array?

    % A=[1 2 3; 4 5 6]---> B=mean(A,2).

how to applay it on an array of the size 10*1*30?

I found the solution.

First squeeze and then apply the mean function

[Rica]

B=mean(squeeze(A),2)

There is no need to squeeze:

B = mean(A, 3)

The result is [10 x 1], because trailing singleton dimensions are reduced automatically, e.g. [10 x 1 x 1] gets [10 x 1] without calling squeeze.

Try size(zeros(10, 1, 1)).
