用matlab基本算法之一，MUSIC方法估计波达方向(One of the basic algorithm with matlab, MUSIC DOA estimation methods)

三次样条插值函数，可以直接调用，本人亲测过来，用了matlab现成的函数在里面(Matlab cubic spline interpolation function can be called directly)

通过一系列教学实例，帮助学生很好的理解matlab中的符号运算实现微分、积分（定积分与不定积分）、极限、级数、绘图等常用功能，几乎可以推导高数中的绝大部分公式，也可用于理论公式推导。(Through a series of teaching examples to help students a good understanding of symbolic computation matlab achieve differentiation, integration (with the definite integral indefinite integral), ultimate, series, graphics and other commonly used functions can be derived almost most of the high number of formulas can also be used to derive theoretical formulas.)

tftb-0.2 时频工具箱,基于matlab实现的(The time-frequency tool box implemented in matlab.)

this is machine mechanism in PID control of Motor whit zero-impulse used in matlab, draw freq fig.

小波去噪 用了几种不同的方式进行限制，有软域值，硬域值还有新开发的一种方式(wavelet)

file to reconize speech

This file is the programs of (chapter 9) of book (Modeling the Wireless Propagation Channel a Simulation Approach with MATLAB) which is related The Land Mobile Satellite Channel. It helps you to simulate The Land Mobile Satellite Channe.

该程序为微粒群算法与遗传算法求解pid参数整定MATLAB程序，优化结果包含参数输出与参数曲线变化图。(The program solves the PID parameter tuning MATLAB program for particle swarm optimization and genetic algorithm, and the optimization results include parameter output and parameter curve change diagram.)
