hi,
i am trying to use a free toolbox which implements Support vector machines in
MATLAB. Now i have to use this toolbox and cannot use some other toolbox due to
some constraints. The problem which i am having is that, this toolbox is using
some C/C++ files (for efficiency). The toolbox has very little documentation and
only says that use 'mex' to compile the C/C++ files on your machine.
When i compile these files (using the following syntax)
>> mex D:\svm\svm_v0.55\@smosvctutor\smosvctrain.cpp
i get the following error:

Unable to complete successfully
Can anyone please tell me where i am going wrong as i dont have any prior
experience in making dll's in MATLAB using C/C++ code.
Thankyou,
