Hi All,<br><br>Here are patches that I"ve been working on<br><br>Polynomial_new_class.patch<br>* root solving class Polynomial.*xx<br>* now using std::vector instead of CLAM::Matrix<br>* using float.h<br><br>LPModel_add_ToRoots.patch

<br>* member function to LP model that calls the root solving function of the Polynomial class<br><br>FormantExtractor_for_NetworkEditor.patch<br>*a network editor processing that outputs a SpectralPeakArray of formants<br>

<br>ProcessingTree_register_FormantExtractor.patch<br>*registers the FormantExtractor processing in the Network Editor.<br>(the attached clamnetwork files demo it).<br><br>One thing that I wanted to get feedback on for a possible future refactoring of the root solving functionality.  Right now it's implemented as a function call, but the more I get familiar with clam methodology, it seems like it would be very clam-ish/clammy  to do it as a processing, where the data in would be a polynomial and the output would be an array of roots.  However, maybe this is overkill and it makes more sense to just keep it as a member function.  

Thanks for any feedback, Abe PS, when I was running scons in the test directory, I had compiling problems, I think b/c of cppunit (the original error is scons: Reading SConscript files ... Package cppunit was not found in the pkg-config search path.

Perhaps you should add the directory containing `cppunit.pc' to the PKG_CONFIG_PATH environment variable No package 'cppunit' found scons: done reading SConscript files. scons: Building targets ...
