IEEE Standard for Digitizing Waveform Recorders (IEEE Std 1057): Algorithm for least squares fit to sinewave data using matrix operations:
- three-parameter (known frequency, non-iterative) and
- four-parameter (general use, find frequency iteratively).
Added features:
- Complex sinusoid fit enabled.
- Alternative 4-parameter fit by using the function fminbnd.
