Math-FFT-0.27
River stage one • 2 direct dependents • 2 total dependents

Changes for version 0.27

  • add method to calculate root mean square of data (suggested by Robert Hiller)
  • in calculating the power spectrum, use same logic for segments = 1 as is currently done for segments > 1 when "number" is specified (suggested by Robert Hiller)
  • in calculating the power spectrum, check if data size is an integral power of 2 if segments is not specified or if segments = 1 and "number" is not specified
  • in the spectrum method, change the name of the "hamm" window function to "hann" (suggested by Robert Hiller). For backwards compatibility, "hamm" is still supported.
  • in the pod for the spctrm method, clarify how options are to be passed in (suggested by Robert Hiller)
