How can I specify a path to save MAT-file

Hi, I am trying to import csv-file and save as mat-file. One thing I don't figure out is that the way to save mat file into a different folder from the *.m(that converts files).

    [varX] = importfile(filename);
    [path, name, ext] = fileparts(filename); 
    extention='.mat';
    matname=[name extention];
    save(matname) %QUESTION!! How to specify the folder?

    save(matname, 'varX')

Dear Walter Roberson

Thank you very much! It helped me a lot. Small thing: fillefile() --> fullfile()
