Hi,

Try this :

d=dir(fullpath(dirname,'*.mat'));
for i=1:length(d)
  load(d(i).name     % will leave whatever variable is in mat-file in memory
  [p,n]=fileparts(d(i).name);         % get path, name w/o extension
  csvwrite([fullfile(p,n) '.csv'],X)  % write to name w/ .csv extension
end

Hi Pankhuri,

Thanks a lot for answering my query.I am able to read all the files by creating a directory. But when I am trying to open those files in excel, I am able to get data of iat matrix only which contains double datatype. TestCase is a structure with 11 fields in each file but I am unable to see that data. Please let me know how I can get complete data from the mat files, one being a double and another a structure. However, the number of elements in each file are same.

Please let me know, how can I read both the structure type and matrix from each file with same variables.
