Default Waveform generator (C#, C++, .NET?)

Hi,
I am getting into developing DSP algorithms in C#, and face the problem o
generating 'test' waveform.

I have been an extensive user of Matlab/Simulink, where you have access t
a
whole library of 'sources' with all the parameters one needs (frequency
sample rate, sine, triangular, even bitwidth...)

Although I 'know' how to code up a 'for-loop' with sin(wt), I know tha
there are a lot of pitfalls and corner cases that need to be considered
Any of you DSP guys know of a good, reliable 'waveform generator' librar
written in either C, C++ or C#?

I tried searches on the languages newsgroup but didn't find anythin
really reliable or complete. I guess this might be more a 'DSP' develope
need?

Thanks,
Dave

If you like the waveform generators in Matlab, and you want to generat
'test' waveforms, then you could use Matlab to create your waveforms an
save them to files. Then in your C, C+ or C# code you just need to ope
the file and read out the samples. I have used this method in the past t
generate DTMF (telephone) tones for testing.

why break head for this c or c++,
there is c++ library for
signal processing and communication functions..that is IT++..please
find those at this link

http://itpp.sourceforge.net/current/

thanks
