NAME

cefft - complex FFT


SYNOPSIS

 void cefft (x,lx,isign,scale)


INPUT PARAMETERS

x - complex*
       input/output array
lx - int
       length of complex array; 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 along one trace.
