Hello everyone, I have 20 .mat files in the same folder and named like following:
data_1, data_2, data_3, ...data_20
and each has 2 tables and 2 variables inside
is there an easy way to import/load these files in a loop or with a command?
Thanks in advance

for z=1:20
filename = ['data_', num2str(z)];
s(z) = load(filename); % Load variables into a structure
end

let's say you are in the directory, then:
matFiles=dir ('*.mat'); %finds all the .mat files (struct)
[NoF,~]=size(matFiles);
for ii=1:NoF %loops through them
matFileName=matFiles(ii).name; %get their name (string)
load(matFileName(1:end-4); %load them, cutting the '.mat' extention from the string
end
probably there is some better or faster method but this should work.
This also works for any generic .mat file regardless of the name as long as you are in the same directory.
