信号的时移 y(t) = x(t - t0) 其中，t0为位移量。若t0为正数，则y(t)等于将x(t)右移t0秒之后的结果(This program is used to implement the time-shift operation )

通过同步压缩小波变换，实现信号的分解和重构，效果优化小波变换(The signal is decomposed and reconstructed by synchronous compression wavelet transform, and the effect is optimized by wavelet transform)

this tuturial is a basic of Matlab.This document is a guide for Matlab begginers and for people who want to be an experts,too.

Matlab版俄罗斯方块，个人一直认为，这个游戏或者说这个程序很经典！ 如果你能掌握这个程序，你对Matlab的外功已经不成问题，回家修炼一下内功，就能毕业了！！ 不说别的，先来玩玩，别忘了把音箱打开！感受儿时的乐趣 程序作者：Pascal Getreuer (Matlab version of Tetris, individuals have always thought that this game or that the program was classic! If you can master this program, you have no problem Matlab' s external work, home practice about internal strength, we can graduate! ! If nothing else, the first to play, do not forget to turn on speakers! Experience the fun process of childhood: Pascal Getreuer)

repval(X) finds all repeated values for input X, and their attributes. (The input may be vector, matrix, char string, or cell of strings Y=repval(X) returns the repeated values of X [RV, NR, POS, IR]=repval(X) returns the following outputs RV : Repeated Values (sorted) NR : Number of times each RV was repeated POS : Position vector of X of RV entries IR : Index of repetition Example: X=[1 5 5 9 5 5 1] [RV,NR,POS,IR]=repval(X) Output: RV = [1 5] Numbers 1 and 5 are repeated values NR = [2 4] Respectively repeated 2 and 4 times POS = [1 7 2 3 5 6] Position index of X for repeated values IR = [1 1 2 2 2 2] Corresponding to which index of RV )
