There is a file named abc.m, but I'm not sure the name is abc.m or Abc.m.
How to determine the true name of file?
I have a test with the true name of file is abc.m
a=dir('abc.m') %a.name=abc.m
and
b=dir('Abc.m') %b.name=Abc.m,
So, I don't know how to deal this question.

d = dir('*.m');
match = strcmpi({d.name}, 'abc.m'); % [EDITED] strcmp*i*
Name = d(match).name;
Another implementation: FEX: FileRealCase. This adjusts the upper/lower case of the path also.

I think the correct function is case-insensitive string comparison with strcmpi:
match = strcmpi({d.name}, 'abc.m')

d=dir('*.m');
f1=char(d.name);
f=upper(f1);
idx=find(cellfun(@(x) isequal(x,upper('Abc.m')),cellstr(f)));
out=f1(idx,:)

There is no reason to convert the names into a CHAR matrix f1. Instead of ISEQUAL inside a CELLFUN, STRCMPI compares directly.
