Programming the coherence function using Advanced Analysis Library

[BiomedGuy]

Hello,

I am trying to program the standard coherence function:  Γ²_xy( f ) = |G_xy( f )|² / [G_xx ( f )G_yy( f )]  in VC++ using the advanced analysis library. 

First I tried:

  CrossSpectrum(pSignal1, pSignal2, iItemCount, pMag, pPhase);
  Spectrum (pSignal1, iItemCount);
  Spectrum (pSignal2, iItemCount);

  loop through all points (i):

  pResult[i] =  ( pMag[i] * pMag[i] ) / (pSignal1[i] * pSignal2[i]); 

Then I started using AutoPowerSpectrum, CrossPowerSpectrum, etc... and couldn't find the right combination.  Has anyone implemented this before?

Thanks,

Marc
