As far as I understand your question I don't see why you would want to do that.

Can you explain in a bit more detail what you mean and what you want? Have a read here and here. It will greatly improve your chances of getting an answer.

For example, I load data from file name a.txt, therefore i want to save output from workspace with name a.mat. How to do it automatically if I have a lot files?

You can use code like this in a loop.

file_name_including_dot_txt='example.txt';
data=function_that_reads_your_file(file_name_including_dot_txt);
[p,fn]=fileparts(file_name_including_dot_txt);
matfilename=fullfile(p,[fn '.mat']);
save(matfilename,'data')

Hello Rik, if I want to save it in a folder how can i change the last line of your code? kindly clarify

[Rik]

Edit the second to last line. That is where the location and file name is determined. What exactly do you mean by saving in a folder?
