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!

sum(cat(3, inpt{:}), 3)
is one way to do it. Basically, concatenate your matrices along an extra dimension and sum along that dimension.

Hi Xiaohan
first get the size of inpt
[sz1 sz2]=size(inpt)
and sum the cell2mat version of inpt
sum(reshape(cell2mat(inpt),13,13,sz2),3)
if you find my answer useful would you please mark it as Accepted Answer?
thanks in advance for time and attention
John BG
