4.77 sddssinefit

• description:
  sddssinefit does a fit to the form:
  y = <constant> + <factor> * sin(2*PI*<freq>*x+<phase>)
• examples:

  sddssinefit <inputfile> <outputfile> -columns=x,y

• synopsis:

  sddssinefit [inputfile] [outputfile] [-pipe=[input][,output]]
   [-fulloutput]
   [-columns=x-name,y-name]
   [-tolerance=value]
   [-limits=[evaluations=number][,passes=number]]
   [-verbosity=integer]
   [-guess=[constant=constant][,factor=factor][,frequency=freq][,phase=phase]]
   [-majorOrder=row|column]

• files: The input file contains both the independent and dependent columns y-name and y-name. The output file contains the independent column along with fitted column y-name and y-nameFit.
• switches:
  • -fulloutput — Includes y-name and y-nameResidual in the output file.
  • -columns=x-name,y-name — The independent and dependent columns.
  • -tolerance=value — Desired tolerance of simplex minimization. Negative values are
    fractional, positive numbers are absolute. Default: 1e-6.
  • -limits=[evaluations=number][,passes=number] — Evaluations and passes for
    simplex minimization. Default: evaluations=100, passes=5.
  • -verbosity=integer — Increases verbose messages. Valid values are 0-4.
  • -guess=[constant=constant][,factor=factor]
    [,frequency=freq][,phase=phase] — Initial guesses for simplex minimization.
  • -majorOrder=row|column — Specifies the binary SDDS layout.
