How do I split a text file at specified points?

Hi,

The text file I want to split into several files is of the following format:

$logE_b4			
1	-2.705351823	41.20420904	1019.694408
2	-2.705336056	41.20422133	1019.888748
3	-2.705316622	41.20423859	1019.4342
4	-2.705258211	41.20426163	1019.306503
$logE_b6l			
31	-2.705282293	41.20410169	1023.670194
32	-2.705316372	41.20405454	1023.15101
33	-2.70534887	41.20400166	1022.14706
34	-2.705389111	41.20394017	1020.771686
$logE_b6u			
62	-2.705099405	41.20418307	1022.253319
63	-2.705171225	41.20413981	1024.090526

I now want to split it into several files at the $ sign and give it the filename after the $, e.g. logE_b4.

Can somebody please help me?

% Load the file
file = fileread('mytextfile.txt');

% Split the data at $
data = regexp(file,'.logE','split');

You may end up with an extra empty cell or two, but that should do what you're looking for.
