I have a small Matlab m file which uses matlab signal processing toolbox, it basically is filtering noise from my signals. I want to run it outside MatLab environment. How can I make it an exe file so that I can run it in dos?
here is my m file
[b,a] = butter(9,.02,'low'); x=textread('noisy.out'); y=filter(b,a,x); save filtered.out y -ASCII
my compiler is
Lcc C version 2.4 in
when I run the following command
mcc -m myfilter.m -o mehdi
to make exe file I get the following error
Error: File "myfilter" is a script M-file and cannot be compiled with the current Compiler.
please help me how I can resolve this problem?

At the top of your file, you need to add
function myfilter
to convert it from a script in to a function.
Note: I seem to recall that filter design was one of the things you are not allowed to compile, so I don't know if you will be able to compile calls to butter() .

I put function myfilter but did not work
do I need to use another compiler to make it work?

What happened when you added that line? What message(s) did you get?
You seem to be using Windows; which Matlab version are you using, and are you using the 32 bit or 64 bit version?

Yes I am using 32 bit windows.
I am trying to build a compiler as you see below
>> mbuild -setup
Please choose your compiler for building standalone MATLAB applications:
Would you like mbuild to locate installed compilers [y]/n? y
Select a compiler:
[1] Lcc C version 2.4 in D:\MATLAB7\sys\lcc
[0] None
Compiler: 1
Please verify your choices:
Compiler: Lcc C 2.4
Location: D:\MATLAB7\sys\lcc
Are these correct?([y]/n): y
Try to update options file: C:\Documents and Settings\Erik\Application Data\MathWorks\MATLAB\R14\compopts.bat
From template: D:\MATLAB7\BIN\WIN32\mbuildopts\lcccompp.bat
Done . . .
--> "D:\MATLAB7\bin\win32\mwregsvr D:\MATLAB7\bin\win32\mwcomutil.dll"
DllRegisterServer in D:\MATLAB7\bin\win32\mwcomutil.dll succeeded
--> "D:\MATLAB7\bin\win32\mwregsvr D:\MATLAB7\bin\win32\mwcommgr.dll"
DllRegisterServer in D:\MATLAB7\bin\win32\mwcommgr.dll succeeded
after setting up the dll files I use this command to make my exe file
mcc -m myfilter.m -o myfilter
But I fail and this is the error message I got
??? Error: File "myfilter" is a script M-file and cannot be compiled with the current Compiler.
Thanks

As Walter suggested, you need:
function myfilter
[b,a] = butter(9,.02,'low'); x=textread('noisy.out'); y=filter(b,a,x); save filtered.out y -ASCII
It doesn't seem like you've added function myfilter to the top of your script to convert it to a function.
@Walter: MATLAB Compiler should support the BUTTER function (see http://www.mathworks.com/products/compiler/compiler_support.html)
