I have a structure containing 557 376 x 376 double matrices. How do I concatenate the 2D matrices to create a 3D matrix with the size 376 x 376 x 557?

I tried this, but didn't seem to work:
data_cell = struct2cell(data)
% convert structure into cell to be able to access individual matrices
% Individual matrices are accessed as follows: matrix_n = data_cell{n,1}.matrix
for k = 1:557
data_3D_matrix = cat(k,data_cell{k,1}.matrix)
end

"Concatenate 2D matrices into one 3D matrix with for loop"
Is there a particular requirement to use a FOR loop?

Thanks! But now I'm getting a structure with the dimensions 1x1x557 that has the string 'matrix' in it and not the actual 376x376 matrix of values...
