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

本matlab程序用惩罚函数法求解多元模型的最小值（给出初始点和精度要求条件）。(The matlab program for solving the minimum multivariate model with penalty function method (given initial point and precision conditions).)

To compute velocity and displacement from Acceleration data In put : Acceleration data and sampling rate in time (delta time) Out put : time. acceleration, velocity, and displacement.

It should be noted that there is still room to improve the speed and the memory usage of the algorithms, using for instance displacement structure algorithms for the RQ decomposition and Lanczos algorithms for the SVD.
