Why does dir('*.mat') not list all of the .mat files in directory?

Hello,
I'm trying to create a structure file which lists all of the .mat files in my directory:
files = dir('*.mat')
This code returns a 4x1 structure, but I have 8 .mat files in the directory. All 8 of the .mat files are the same format (i.e. 3 variables per .mat file). Can anyone tell me why my other .mat files are not being listed in the struct file?
Thanks, Dan

Are you sure about those files being in there? Does WHAT see them (type: what) in there?
D = dir;
length(regexp([D(:).name],'\.mat')) % What does this say

try this
d=dir
d1=struct2cell(d);
d2=d1(1,:);
d3=cellfun(@(x) regexp(x,'.mat'),d2,'uni',false)
d4=find(~cellfun('isempty', d3))
files=d2(d4)'

~cellfun('isempty', d3) is faster than ~cellfun(@isempty, d3), which is faster than cellfun(@(x) ~isempty(x)).
