SPFFTPT

The SPFFTPT routine computes a slow Fourier Transform
            from Fourier space to a set of gridpoints.

USAGE:    CALL SPFFTPT(M,N,INCW,INCG,KMAX,RLON,W,G)

   Input argument list:
      M        - INTEGER FOURIER WAVENUMBER TRUNCATION
      N        - INTEGER NUMBER OF GRIDPOINTS
      INCW     - INTEGER FIRST DIMENSION OF THE COMPLEX AMPLITUDE ARRAY
                 (INCW >= M+1)
      INCG     - INTEGER FIRST DIMENSION OF THE GRIDPOINT ARRAY
                 (INCG >= N)
      KMAX     - INTEGER NUMBER OF FOURIER FIELDS
      RLON     - REAL(N) GRID LONGITUDES IN DEGREES
      W        - COMPLEX(INCW,KMAX) FOURIER AMPLITUDES
 
   Output argument list:
      G        - REAL(INCG,KMAX) GRIDPOINT VALUES
