derive program

Documentation for the derive program is below, with links to related programs in the "see also" section.

{   version = 1.02; (* of derive.p 2007 Mar 13}

(* begin module describe.derive *)
   derive: compute the derivative curve for a xyin

   derive(xyin: in, derivep: in, dxyin: out, output: out)


   xyin:  input file for the xyplo program

   dxyin:  derivative of log of values from the xyin

   derivep:  parameters to control the program.  The file must contain the
      following parameters, one per line:

      parameterversion: The version number of the program.  This allows the
         user to be warned if an old parameter file is used.

      (Missing parameters to determine columns, defaults to 1 and 2
      for x and y.)

   output: messages to the user


   Compute the derivative of the curve by finding the differences of
   the y values divided by the differences of the x values.

   Only columns 1 and 2 can be used for now.  The code for
   chosing arbitrary columns has not been written.
