How can I read file names and convert them to a matrix? I have more than one file and I want to read their contents in one loop of the program. Thanks

no I need to read the contents of a specific folder's file names (as text), then run selection rule to pick names only that i want.
The problem is that files being send to a folder, with names of the format (yyyymmddhh.jpg) so each day there is a marked file as (yymmddT.jpg)... (T for terminate). The names are varying, i can't read all by fopen commands, i can't specify the required name unless they are in some form.

Download a function file called folderFiles.m.
It'll do the job for you, hopefully.

doc dir
D = dir([myfolder 'my*file*name*.*']);
files = {}';

This means, that no file matchs the filter:
'C:\Documents and Settings\John\My Documents\MATLAB\Pic_Down*.jpg'
Perhaps you want:
'C:\Documents and Settings\John\My Documents\MATLAB\Pic_Down\*.jpg'
Note: fullfile() is much better for constructing file names than STRCAT, HORZCAT or [.].

It is always a good idea to read the FAQ, because it is efficient to profit from the errors of others.
