smooth

• name:
  smooth
• synopsis:

  smooth inputfile [ outputfile] [-smooth= odd_integer] [-passes= integer] [-threshold= level]

• description:
  smooth smooths a data set by multipass averaging over adjacent points, and will also eliminate points with ordinate values smaller than a specified threshold.
• files:
  inputfile contains the data set to be smoothed. The result is placed in outputfile, or back in inputfile if no outputfile is given.
• options:

  smooth

  
  Specifies the number of adjacent points to average over. This must be an odd number. The default is 3.

  passes

  
  Specifies the number of smoothing passes to make over the data set. The default is 1.

  threshold

  
  Specifies a level such that points with ordinate values smaller in magnitude than this threshold after smoothing are deleted from the output.
