Coordinate Transformation between several frames of reference, developed in MatLab

说明：  广义S变换 作为小波变换和短时傅里叶变换的继承和发展， S 变换采用高斯窗函数且窗宽与频率的倒数成正比，免去了窗函数的选择和改善了窗宽固定的缺陷，并且时频表示中各频率分量的相位谱与原始信号保持直接的联系，使其在 PQD 分析中可以采用更多的特征量，同时， S 变换提取的特征量对噪声不敏感，因此，近年来众多学者纷纷采用 S 变换并结合其他分析工具应用于 PQD 的分析，产生了大量研究成果。(Generalized S-transform)

music change speed中，jiasu.m是让一首音乐旋律速度加快播放，jiansu.m是让一首音乐旋律速度减慢播放，两个情况下都不改变音乐的基调。(Music change speed, jiasu.m is to allow a faster melodic playing, jiansu.m is to make a musical rhythm to slow down play, the two cases do not change the tone of music.)
