MATLAB: How to sum same size cell blocks

Question

Hi all,

I have a cell which contains same size matrices, like this:

inpt = 
      [13x13 double]    [13x13 double]    [13x13 double]    [13x13 double]

Is there a function to sum blocks within a cell? So the result would be a [13*13] matrix with elements of same entry summations of inpt.

Many thanks!

Answer 1

 sum(cat(3, inpt{:}), 3)

is one way to do it. Basically, concatenate your matrices along an extra dimension and sum along that dimension.
