  • GASDEV: normally distributed deviate of zero mean and unit var
  • TWOFFT: complex FFTs of two input real arrays
  • REALFT: FFT of a set of 2N real valued data points
  • FOUR1: forward or inverse FFT of the input array (removed)
  • LUDCMP: LU decomposition of a square matrix
  • LUBKSB: backsubstitution to solve a system
• noao/onedspec/splot/spdeblend.x
  • GASDEV: normally distributed deviate of zero mean and unit var
• noao/rv/numrep.x
  • FOUR1: forward or inverse FFT of the input array (removed)
  • REALFT: FFT of a set of 2N real valued data points
  • TWOFFT: complex FFTs of two input real arrays

All marked items are handled – either by replacing with free code, or by removal (which is then marked in the text). This fixes #21.
