convol

• name:
  convol
• synopsis: convol { signal response.in convolution.out | -deconvolve convolution.in response.in signal.out [-noise_fraction= value] } [-format=" format-string"]
• description:
  Performs discrete Fourier convolution or deconvolution of two data sets, assuming that the range and number of points is the same for both sets.
• files:
  For convolution, signal and response.in contain the signal and response functions, respectively; the result is placed in convolution.out. For deconvolution, convolution.in and reponse.in contain the function to be deconvolved and the response function with which to deconvolve it, respectively; the result is placed in signal.out.
• options:
  

  format

  
  Specifies a C-style format string for printing the data to the output file.

  noise_fraction

  
  Specifies a fractional noise floor to be invoked to prevent divide-by-zero errors during deconvolution. Any denominator less than this fraction of the maximum absolute value of the FFT of the response function, will be replaced by said fraction of the maximum value.

  deconvolve

  
  Requests that deconvolution be performed, rather than the default convolution.
