Hello,
I seek help in accessing files with a particular extension using the dir command. However, I intend to use a variable name inside the dir command instead of explicitly mentioning the path name. Here is the reference code:

Dirname = uigetdir('C:\Documents\MATLAB\TempFolder');
directory = dir(Dirname);

Line 2 gives all files in the directory accessed by the variable name 'Dirname'.
However, to selectively extract say only .m files, I cannot use the '*.m' wildcard operator as follows:
directory = dir(Dirname *.m);
This is a line parse error.
Did not find help with regard to this in documentation too.
How do I use the wildcard operator in this case?

You forgot the backslash at the end of dirname.

Dirname = uigetdir('C:\Documents\MATLAB\TempFolder');
pattern = fullfile(Dirname,'*.m');
directory = dir(pattern);
