Extract the date from a standard filename

Hi Guys,
I have thousands of .MAT files which hold data with the file name convention
Vehicle_Registration_Type_Date.MAT
the Type is exactly the same for every file.
Currently I am using
DateLocation=regexp(SelectedMat,'\d');
DateVals=regexp(SelectedMat,'\d','match');
DateVal = cell2mat(DateVals);
DateNum = datenum(DateVal,'yymmdd');
DateStr = datestr(DateNum, 'dd-mm-yy');
I am finding that the 2 digits in the Registration are appearing in the datestring making it wrong.
e.g Vehicle_XX62XXX_Type_130101 returns 62130101
The date is in US format yymmdd although I am in the UK
is there a way to filter the string to only be searched after type?
Any help would be greatly appreciated
Many Thanks
James

Str = 'Vehicle_XX62XXX_Type_130101';
index = strfind(Str, '_');
S = Str(index(end):end);
StrDate = [S(5:6), '-', S(3:4), '-', S(1:2)];
This is a really stupid approach, without 2 REGEXPs, CELL2MAT, DATENUM and DATESTR, which are all such powerful, that they need a lot of time.
