sprintf to make filenames

[Mike Miller]

Hello all--

I want to be able to use the usual save command of this form:

save -ascii file_0001.dat matrixdata

but I'd like for the filename to be determined by a variable in this sort
of way:

i=1;
save -ascii sprintf("file_%04d.dat",i) matrixdata

That doesn't work because Octave doesn't seem to interpret the sprintf
command to produce the string for the filename.  How can I get this to
work?

TIA,

Mike
