Subroutines:
- offt
- OFFT calculates fast fourier transform of an input array F
- offt0
- OFFT0 initializes sines and cosines used by OFFT routines
- offte
- OFFTE calcs. spectral energy E from input gridpoint values F
- offti
- OFFTI performs an inverse fast fourier transform
Global Variables:
- km :
integer*4, parameter
- length of input array; to change KM => rewrite module !!!
