Does matlab compiler support randn function?
|

| I compiled the following code with VC6 in Windows XP sp2 successfully.
However, when I run test.exe, I got the following message. The test.m
file runs ok in the matlab. So it seems like matlab compiler does not
support randn.
I think randn is a very basic function which should definitely be
supported. Does any have similar experience? I uses mcc -m test.m to
build the exe file.
??? Error using ==> randn
Unknown command option.
Error in ==> test at 5
MATLAB:badopt
Compiler Name version: MSVC 6
============================ test.m ==============================
function y = test(N)
tic;
for i=1:10
for j=1:10
a=randn(N,N);
b=randn(N,N);
c=det(a);
d=fft(b);
e=a.*b;
end
end
toc

| What input did you give to your test function? This can happen without the
compiler as well:
??? Error using ==> randn
Unknown command option.

| Hi,
keep in mind, that compiled applications always get their paremeter as
strings, so you need to do something like
if isdeployed
N = str2double(N);
end

| I use "test 1000" in the windows command line. In matlab, test(1000)
works just fine.

| I found out what's wrong. The argument is of char data type. After I
add N = str2num(N);, the problem is gone.
Thank you for reminding me this. Too  , the test.m does not run
faster after compiling. But this still help me to run it on the
cluster.
