How to create a .mat file corresponding to a .txt file, as per user input?

I have files in my Matlab directory in the form 'Phase3Subject1.txt', 'Phase3Subject2.txt',...'PhasexxSubjectyy.txt'. How do I take inputs for xx and yy from the user, and create the corresponding .mat file showing all the data stored in the .txt file? For example, if user gives input xx=2, yy=14, it should create 'Phase2Subject14.mat' file and show all the data that was stored in 'Phase2Subject14.txt'. Please give the entire code.

Can you give more details about the data in your text file?

xx=2;
yy=14
filename=sprintf('Phase%dSubject%d.txt',xx,yy)
data=dlmread(filename)
save(filename,'data') % Save in a mat file

Thank you so much! I have another doubt. My file 'PhasexxSubjectyy.txt' contains a 2400x66 matrix of data (voltages). What do I do if I want to display all the odd numbered columns in one matrix of 2400x33, and all the even numbered columns in another matrix of 2400x33 in the file 'PhasexxSubjectyy.mat'?
