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 transformation, is the more popular time-frequency analysis algorithms, can be used for seismic data analysis and time-frequency spectrum analysis, the program based on matlab platform realize the s transform and inverse transform.)

对信号进行取样，抽取，并将其与原信号对比(The signal sampling, extraction, and compared with the original signal)

说明：  以450,545,700nm三个波长为三基色画出的麦克斯韦颜色三角形，求其中任意一点的光亮度比(The Maxwell color triangle is drawn with three wavelengths of 450545700nm as the three primary colors, and the brightness ratio of any point is calculated)
