RE: Using a string variable as a filename

[William Krekeler]

To print a figure to a specific filename. You can replace gcf with a figure 
handle. Also I default to saving to png so you would need to change the flag 
and filename end.

figure, plot( 1:10 );
outputPath = pwd;
counter_in_loop = 1;    % just added to put something in the sprintf to show 
that filenames can be built from variable content
print( gcf, '-dpng', fullfile( outputPath, ...
 sprintf('some_file_name_%d.png', counter_in_loop) ) );
