Hi,

I am trying to use a file name as a title for a set of axes. The code I am using looks like this:

set(get(gca,'Title'),'String',file_name);

where file_name is a variable containing, well, the name of a file.

the problem is that the file name contains underscore characters, which are interpreted as signaling subscripts, so the axes title has little subscript characters instead of underscores. is there a way to disable this somehow? or am I resigned to having to code a find/replace for _ into \_ ?

That's easy enough...

set(get(gca,'Title'),'String',strrep(file_name,'_','\_'));

Question---

what's wrong w/ title() instead since using gca, anyway?

OK, alternatively...

h = title,file_name); set(h,'interpreter','none')

Of course, this disables all tex interpretation so any other enhancement
would be lost if there were any. Granted, not likely in a filename but
as a general rule.

Hah I did not know that title() existed! Thanks for the pointer.
