Question
Can someone explain how to combine .mat files present in workspace or in directory into one .mat file? The problem is that the files are not properly named and the files have different rows but same number of coloumns.

Assuming that each .mat file contains exactly one array with compatible sizes:

 

D = 'path to the directory where the files are saved';
S = dir(fullfile(D,'*.mat'));
N = numel(S);
C = cell(1,N);
for k = 1:N
    F = fullfile(D,S(k).name);
    C(k) = struct2cell(load(F));
end
M = vertcat(C{:})
save('new.mat','M')
