说明：  hand gesture recognition using pca

this matlab function finds peaks of a plot. it takes a coordinate matrix as an input. also removes redundent peaks (for instance, in case of a step plot, it finds one peak)

维纳自适应滤波设计及Matlab实现，一份word文档，希望会有用。(We simply analyses the wiener2 () which is a adaptive filter in MATLAB.)

very simple watermarking using matlab. to hide a message in cover image..

时域有限差分差分法仿真脉冲在真空以及有损耗和无损耗的介质的一维传播情况(FDTD simulation of a pulse )

cholesky分解，可以放心的使用，已经调试正确了(cholesky decomposition, you can safely use, has the right of the debugging)

在过程控制中，按偏差的比例（P）、积分（I）和微分（D）进行控制的PID控制器（亦称PID调节器）是应用最为广泛的一种自动控制器。(In process control, according to the percentage of deviation (P), Integral (I) and differential (D) control of PID controller (also known as PID regulators) is the most widely used of an automatic controller.)

混沌吸引子，用于处理信号，得到非线性的处理(The chaos attractor, for processing signals, nonlinear processing)

维纳噪声抑制，设计p阶的最优FIR维纳滤波器，估计平均平方误差， 试针对p=12的情况，分别取几个不同的权值(如0.1, 0.5, 1.0)，研究这时的噪声抑制性能。(Wiener noise suppression, the optimal design of p-order FIR Wiener filter, estimated mean square error, try the case for p = 12, respectively, the right to take several different values (such as 0.1, 0.5, 1.0), study time noise suppression performance.)
