What steps will reproduce the problem?
1.when I run "tutorial_ClassRF.m" in matlab2009a,I got these errors:

Error in ==> tutorial_ClassRF at 39
    model = classRF_train(X_trn,Y_trn);

How can I do it ???

hello, thanks for sending the bug report

Though i cannot read what the error message is.

it will be great if you can post what arguments you were passing, so i can 
setup a 
dummy test. 

like, argument1: size NxD and type, you can get that via whos('argument1')

You can also put in a debug point at line 347 or classRF_Train.m and see if all 
of 
these variables are defined at that point. 
X',int32(Y_new),length(unique(Y)),ntree,mtry,int32(ncat),                       

int32(maxcat), int32(sampsize), strata, Options, int32(ipi),                    

classwt, cutoff, int32(nodesize),int32(nsum), int32(n_size), int32(p_size), 
int32(nsample)

if either one of them is non-existent, it will explain the error message.

Sorry i realized that this is happening with the tutorial file so i already 
know what 
parameters are being passed in.

please disregard my earlier comment.

can you tell me the exact error message? all i can see are squares :(

also have you verified that the VC++ redistributable 2005 and 2008 are 
installed?

Thanks for your reply.
I installed vc++ rdistributable 2005(Simple Chinese) on my computer.and when I 
run 
your "tutorial_ClassRF.m", these are all error message show my computer:
As this package has precompiled mex files ignore this file i.e. 
compile_windows.m
    Setting to defaults 500 trees and mtry=4
??? Undefined function or method 'mexClassRF_train' for input arguments of 
type 'int32'.

And I have another question.Did this program could classify data file like this?

About comment 3. You should be able to run that on your data. RF will support 
both 
categorical and real valued data. Categorical meaning that the variable takes 
only 
few values like in your case tcp, udp things like that and real meaning all 
real 
values -inf to +inf. You might have to convert tcp and udp into fixed numbers 
like 
tcp=1, udp=2 and so on. I'll put in a tutorial code on how to use categorical 
here 
soon.

About comment 3 error, can you make sure that everything of the package (folder 
and 
subfolder) are included in the path. mexClassRF_train is a mex32/mex64 file 
that 
comes with the download so it should be there, unless you moved the 
tutorial_classRF.m to some other place.

About comment 4. i know that number 8 (i.e. visual c++ 2008 express) works. 
once this 
is done just run the compile_windows.m file and it will generate the mex files 
mexClassRF_train/predict.mex32 or mex64 (for 64-bit os) that you can see inside 
RF_Class_C folder. Those are the ones that will be needed for the package to run

do tell me if you still encounter problems
