I want to select data piecewise in a loop, and I want to be able to save the files as filename_number, where the number increases for each iteration of the loop. Is there an easy way to accomplish this?
The idea is: first selection, saved file name is file_1 second selection, saved file name is file_2 etc

Easy way to increment your filename is:
filename = sprintf('%s_%d','filename',k)

BaseName='MyDataFile_';
for k=1:10
FileName=[BaseName,num2str(k)]
end

Hi Fangjun, I tried this function and it work with me but when I tried to execute OpenSees.exe, it give me error as the following: BaseName='TS'; for k=1:3 FileName=[BaseName,num2str(k),'.tcl']; !OpenSees.exe FileName end and the message is as the following: couldn't read file "FileName": no such file or directory

You can't use ! if the command you want the system to execute is going to be assembled using the contents of a variable. Use the system function instead, building the command you want the system to execute using concatenation (as you built FileName) or sprintf.
