sin-cos.zip - Cosinor analysis uses the least squares method to fit a sine wave to a
time series. Cosinor analysis is often used in the analysis
of biologic time series that demonstrate predictible rhythms. This
method can be used with an unequally spaced time series.
Follows cosinor analysis of a time series as outlined by
Nelson et al. Methods for Cosinor-Rhythmometry Chronobiologica.

sinefitness.zip - Least squares sinusoid fit algorithm described in IEEE Standard for Digitizing Waveform Recorders (IEEE Std 1057): Algorithm for three-parameter and four-parameter least squares fit to sinewave data using matrix operations.
The algorithm is (in most cases) really quick. If the signal frequency is a guess, it has to be close to true frequency value.
For further information, consult IEEE Std 1057 and/or IEEE Std 1241 documentation.
Now also fits complex sinusoids i.e. phasors with noise and o,2015-01-24 15:25:16,下载3次
