Wavelet-analysis-

半定规划，属于凸优化的一种，matlab 实现的源码，适合学习 Semidefinite Programming(Semidefinite programming, belonging to a convex optimization, matlab source realization, suitable for study Semidefinite Programming)

说明：  这是一个小波变换处理语音信号的matlab程序，用于语音去噪(This is a wavelet transform voice signals in the Matlab procedures used for voice denoising)

通过光速不变原理介绍相对论时间膨胀公式和长度收缩效应公式，并举例进行了说明。用曲线显示时间膨胀与物体速度的关系，显示长度收缩与物体速度的关系。(Through the principle of constancy of light, relativistic time dilation formula and length contraction effect formula, and examples are described. Curve shows the time dilation and the speed of the object, showing the length contraction and the speed of the object.)

The WAVELETCHANGE dialog is initiated by calling WAVELETCHANGEINIT which then calls WAVELETCHANGE. With one exception, WAVELETCHANGE is never called directly from another program. Tha exception is when another program has a figure handle that may be a legitimate WAVELETCHANGE window or not. Calling waveletchange( test ,figurehandle) will return 1 if it is a legit change window and zero otherwise.

这是用matlab编写的fast算法，这是一种速度非常快的角点检测方法，实时性很强。(binary descriptor)

simulates the MPPT algorithm using PSO

用AUTOASSOCIATEIVE MEMORY NET的方法来存1-10个数字(Write a computer program to implement an autoassociative memory net to store the following ten numbers)

说明：  一个关于FM收音机的程序，里面包括FM调制解调，以及PLL模块，并在SIMULIN内实现仿真。(A program on FM radio, which includes FM modulation and demodulation, and PLL module, and simulation within the SIMULIN.)

空气中声传播的fdtd例程，简单可用，希望对大家有帮助(Fdtd airborne sound propagation routines, simply available, we hope to help)

根据读取到的已知控制点的坐标，计算在该区域内的平面转换五参数，该五参数不同于当前使用较多的四参数(According to the known control point to read the coordinates to calculate the plane in the region converted five parameters, the five parameters to use more different from the current four-parameter)
