Hello, I have high number of mat files generated by a system which indexed them. I have files (test1.mat, test2.mat,...test1000.mat) I need to run a loop to extract data from certain variables in these files and process them.

在 MATLAB Online 中打开

You want to process a sequence of files and that shows you how to process a sequence of files.

for K = 1 : 1000
  filename = sprintf('test%d.mat', K);
  data = load(filename);
    disp(size(data.VariableName));  %do something with the data fetched from the file saved as VariableName
  end
