# Calculate mean value of every element of a .mat file

I have a .mat file which contains 300 matrixes all of which have the same dimensions of 256x320. I want to calculate the mean value of each matrix, with a for circle maybe, thus obtaining 300 vectors. Then I want to put all those vectors in a single matrix. Thanks in advance.

What do you mean 300 vectors? Wouldn't the mean over the entire matrix give you a scalar?

S = structfun( @mean, load('yourFile.mat'),'uni',0);
matrix=cell2mat(struct2cell(S));

singleMatrix=zeros(size(oldMatrix));
for i=1:length(singleMatrix)
singlematrix=mean(oldMatrix);
end
that should work if you want your end matrix in a single row
