Question

0 个投票

all_data =[];
files = dir('*.mat');
for q = 1:lenght(files)
  load(files(q).name);
all_data = [all_data D.F];
end

This is my code now but get an error load(files(q).name); saying error in read files... New to matlab so apologise in advance for silly mistakes.

For a basic explanation see the MATLAB documentation:

If all of the .mat files contain the same variables then try something like this:

files = dir('*.mat');
out = load(files(1).name);
for k = 2:numel(files)
    out(k) = load(files(k).name);
end

Your data is available in the non-scalar structure out, e.g.:

[out.F]
