求解抛物型方程的交替隐方向P-R差分格式的matlab程序实现。不过大家在用的时候要用到原函数f.m和精确解函数uexact.m，应用程序的时候只要修改精确解和右端项就可以了。(Solving Parabolic Equations PR alternating direction implicit difference scheme of matlab program. But we can use the time to use the original function fm and the exact solution function uexact.m, whenever an application to amend the exact solution and the right side of it.)

说明：  matlab代码功能实现图像的距离变化，已经通过调试成功！(matlab code image of the distance function changes have been adopted successfully debug!)

基于MATLAB的数字滤波器，带有gui界面(Matlab-based digital filter, with GUI interface)

在阵列信号处理中，一种很经典的信号波达角方向估计方法：MUSIC（多重信号分类）算法。该程序中有三个频率的信号，经过此算法可很好地分辨出这三个信号。(In array signal processing, a classic signal the direction of arrival angle estimation method: MUSIC (multiple signal classification) algorithm. The program has three frequency signals, by using this algorithm,and you can well distinguish these three signals.)

ITD进行模态识别，得到模态参数,ITD 法是一种单输入多输出、基于包含系统参数的自由振动方程识别结构参数的方法，(ITD modal identification, get the modal parameters.ITD method is a single-input multiple-output, based on the structure of the free vibration equation parameters include system identification method parameters,)

说明：  ECG中小波变换定位R波，并绘制墨迹大随尺度变化(wavelet locat R in ECG)

随机共振运用于弱信号检测，同时对于其中的频谱能够很好的分析。(Weak signal detection applied to stochastic resonance, while for the spectrum which can be a good analysis.)

TST matlab 代码可以预测时间序列中的结构性变动点，以及用来进行样本外预测。(TSt matlab code can be useful for identifying structural changes in time series and particularly be helpful for forecasting.)

The LMSE package contains two subroutines. LMSE computes the minimum mean square error (MSE) possible if one image is allowed to be linearly scaled in intensity. LMSEDIFF computes the difference image after the target image is scaled according to the scaling that minimizes the MSE. This is a better way to compare images if the absolute magnitude of the intensity has no meaning.

利用matlab实现语音信号的倒谱分析,通过观察仿真，可以看出倒谱函数的频谱特性。(Matlab voice signal cepstrum analysis, simulation, can be seen by observing the spectral properties of the function cepstrum.)
