Constructing saved file name with variables from code

Hi all

I currently have a save command which labels the saved files with a static name which I change each time

If I have variables such as:

k = 1:10
I= 1:5:100
Date/Time

How can I code this so each file name takes this information for the name,

i.e something like

 Test_File  %datestr(now,30) plus the others.

Thanks for your help!

Do you meansomething like this?

 ext  = '.mat'; %or .cvs, .xlsx, ...
 file_name = ['Test_File_'  datestr(now,30) '_'  num2str(k) '_' num2str(I) ext];

I would recommend you use sprintf:

filename = sprintf('Test_File_%s_%d_%d.mat', datestr(now, 30), k, i);
