说明：  寻找三次样条多项式需要求解大量的线性方程。实际上，给定N个断点，就要寻找N-1个三次多项式，每个多项式有4个未知系数。这样，所求解的方程组包含有4*(N-1)个未知数。把每个三次多项式列成特殊形式，并且运用各种约束，通过求解N个具有N个未知系数的方程组，就能确定三次多项式。 (find cubic spline solving polynomial need a lot of linear equations. In fact, given N breakpoints, it is necessary to look for N-1 cubic polynomial, each with four polynomial coefficients unknown. Thus, by solving the equations contain 4* (N-1) unknown. Each cubic polynomial Timing special form, and use of various constraints, by solving N with N unknown coefficient equations, we can identify three polynomial.)

RIMM与IMM的程序比较，就是两中方法比较哪个跟踪效果比较好(RIMM IMM with the procedure, which is two methods which track the results were quite good)

说明：  s变换，是当前比较流行的时频分析算法，可以用于地震数据时频分析和频谱分析，该程序基于matlab平台，实现了s变换和反变换。(S-transform is a popular time-frequency analysis algorithm, which can be used for seismic data time-frequency analysis and spectrum analysis. Based on MATLAB platform, the program realizes S-transform and inverse transform.)
