i have an easy problem.

i want to load a "mat" or "txt" file.
i use normally
"load test_no1.mat" command

can i break file name into pieces like:
file1=''test_no"
file2=2
file3=".mat"

with changing file2 variable, i can i load other mat files.
how can i do this?
thank you.

filename = [file1 num2str(file2) file3];
load(filename)

one of the many solutions
- SPRINTF is very versatile as it allows you to add other/recurring patterns...

fnma=sprintf('%s%-1d%s',file1,file2,file3);
load(fnam);
