说明：  此文件里包含了关于Matlab的经典程序，对于Matlab的编程有极大帮助，包括差值拟合等等，另附上一个实时时钟的Matlab程序，也比较经典。(This file contains the classical procedures on Matlab, Matlab programming for the great help, including the difference between the fitting and so on, attached to a real-time clock of the Matlab program, but also more classic.)

参数辨识程序，理论基础为递推最小二乘法，实现对系统参数的辨识(parameter identification)

Truss program with finite element method,

基于DFT的瞬时测频算法，及插值算法，最后由图形表示测频结果。(Based on the Instantaneous Frequency Measurement DFT algorithm, and the interpolation algorithm, and finally by the graphical representation of frequency measurement results.)

LADT ECG Compression Algorithm 4

按键式电话如下图所示，当按下某一个键时会产生如图所示的相应的频率模拟信号，并通过对该信号频率的检测，识别出对应的按键。试通过编写一个数字信号分析程序，模拟完成上面的功能。(Touch-tone phone as shown below, when pressing a key will be generated as shown in the corresponding frequency analog signals and, through detection of the signal frequency to identify the corresponding button. Test through the preparation of a digital signal analysis program to simulate the function of the completion of the above.)

这是matlab中实现PID经典控制算法程序(This is the classic PID control algorithm program in matlab)

载波恢复算法的MATLAB实现，很具有参考价值，精度满足要求(practice algorithm for carrier frequency estimate)

LDA 人脸识别的 matlab 源程序 大家看看 可以用的(LDA face recognition matlab source code you can look at the)

说明：  曲波变换1，可以用来做曲波变换得到系数矩阵，其中含逆变换(curvelet Part)
