Thread Subject: Standalone too slow !!

Hi,

I'm a novice Matlab user and currently doing a voice
recognition project in which I have made use of one or two
GUIs as well.
The trouble is that when I create the standalone(.exe) out
of my .m files using "mcc" the resulting application is
performing V E R Y S-l-o-w-l-y... what can I do to fix this?
Any code optimizing techniques would be welcome.

(As an aside - somebody please tell me how I can have the
DOS prompt window NOT to be displayed whenever I run the
standalone (.exe ))

Yours Truly,

Blueblood

Hello
1. Compiling the application wont effect in faster speed.
You will get the same speed in the compiled application
and as well as in the MATLAB environment. Were you getting
satisfactory results running your application in the
MATLAB environment?
2. You can either use this functionality to suppress your
DOS command window

What you need to do is identify the regions of your code
that are consuming the time to process using the Matlab
profiler. First try to optimize the efficiency of these,
e.g. predefining arrays, vectorizing execution etc - if
this helps. If the processing is then still too slow,
rewrite the offending code in C/C++ and configure it into a
mex file.

Hope that helps
