How to import multiple .m files

Is there a simple loop or so to call multiple files and extract the sub structures from it where all .m files have the same substructure?

[Star Strider]

Are you asking about MATLAB script ‘.m’ files or binary ‘.mat’ files?

I`m answering assuming that you are mentioning '.mat' file. ('.m' file is merely a matlab script file..) If the data you want to load has regular name, like 'name1.mat', 'name2.mat'..., I recommend you to use 'eval' function with for loop.

for i=1:10
    eval( ['load(''name' num2str(i) '.mat'')'] );
end

Do not do this. This is pointless usage of eval, which serves no functional purpose at all in this code, and will only make this code slower, buggier, and harder to follow:

Instead of writing cargo-cult code using eval, simply call load directly:

S = load(sprintf('name%d.mat',k))

Thank you stephen, i admit that, your code looks much simpler.

See the FAQ for how to process a bunch of files: http://matlab.wikia.com/wiki/FAQ#How_can_I_process_a_sequence_of_files.3F.

In the middle of the loop, put Stephen's code to store all the structures pulled from your mat files.

matFullFileName = fullfile(pwd, sprintf('name%d.mat',k)); % Whatever.....
S{k} = load(matFullFileName) % Store this file's structure in our structure array.
