关于matlab的一本不错电子书，高级图形，图形与声音，以及matlab与其他语言的混合使用(On matlab' s a good e-book, advanced graphics, graphic and sound, and matlab mixed with other languages)

对三相异步电机的转速调速的MATLAB进行仿真(Simulation of the motor control)

解决了带有time index高斯混合模型的状态估计问题(An estimation technique for Time Indexed Gaussian Mixture Models)

编写M文件，创建如下图形窗口，分别绘制如下图所示的曲线。 （1）曲线y=sin(t)sin(9t)，要求采用红色，点线。横坐标取值范围[0~ ]，标注x轴、y轴并加标题。 （2）一组余弦曲线，其振幅分别为0.4，0.6和0.8。横坐标取值范围[0~2 ]。添加图例与标题。进入图形编辑状态，调整图例的位置。 （3）分别绘制peaks函数的曲面图和网格线图。对曲面图做平滑处理，并添加标题与colorbar。 (Write M file, create the following graphics window, curves were plotted as shown below. (A) the curve y = sin (t) sin (9t), require the use of a red dotted line. The abscissa in the range [0 ~  ], labeled x-axis, y-axis and a title. (2) a set of a cosine curve, and the amplitude was 0.4, 0.6, 0.8. Abscissa value range [0 ~ 2  ]. Add a legend and title. Into the graphical editing mode, adjust the position of the legend. (3) were drawn surface chart peaks function and grid line graph. Surface charts do for smoothing and add titles and colorbar.)

小波分析,包换小波降噪，分解和重构，频谱分析(Wavelet analysis, replacement wavelet noise reduction, decomposition and reconstruction, spectrum analysis)

原来先进PID控制MATLAB中的大林算法例子在高版本的MATLAB中运行有较多错误，这是我经过修改，在MATLAB7.11.0中调试成功的代码。(The original advanced PID control the Daelim algorithm in MATLAB example high version of MATLAB run more error been modified, code debugging success in MATLAB7.11.0.)

Basic function to locate and measure the positive peaks in a noisy data sets. Detects peaks by looking for downward zero-crossings in the smoothed third derivative that exceed SlopeThreshold and peak amplitudes that exceed AmpThreshold. Determines, position, height, and approximate width of each peak by least-squares curve-fitting the log of top part of the peak with a parabola.

内共有两个程序：1.用Mallat算法实现一维小波变换；2.用DWT实现二维小波变换。 从仿真图可以加深对小波概念及小波变换的原理。(A total of two procedures: 1. Mallat algorithm using one-dimensional wavelet transform 2. With the realization of two-dimensional wavelet transform DWT. From the simulation wavelet map can deepen their understanding of the concept and the principle of wavelet transform.)

自己编的matlab厂程序。这是将局部坐标系的坐标转化为球面坐标系的坐标，非常实用。(own addendum to the Matlab plant procedures. This is the will of local coordinates into spherical coordinates, very practical.)
