Checking the existence of any file with a specific extension in a directory

I require to check whether any file exists with a specific extension in a given folder. Let us say, I look for whether any .pdf file is present in my working directory. MATLAB does not accept wildcard commands like

exist('*.m')

Any solution?

Use dir instead. If you only want to know about the existence, then you could simply check if the returned structure is not empty:

~isempty(dir('*.m'))
