NAME

cvfft - Complex fft


SYNOPSIS

     void cvfft (x,lx,nx,isign,scale)


INPUT PARAMETERS

x - complex
       input/output array
lx - int
       length of complex vectors
nx - int
       number of vectors; must be a power of 2
isign-int
       sign of sqrt(-1)
scale-double
       scale factor; sqrt(1./lx) conserves energy


DESCRIPTION

     Complex fast Fourier transform between vectors of an array.  
     Cvfft takes a 2D panel and does a complex fast fourier
     transform across the second dimension, of all the time 
     samples. The arguments are as follows:
