Quadrature-Component-Analysis

对一种三相无源功率因数校正电路进行了参数的优化和仿真，仿真结果表明，运用Matlab中的SimPowerSystems模块对复杂的电路进行仿真分析和研究，不失为一种准确、直观有效的方法。 (Of a three-phase passive power factor correction circuit parameter optimization and simulation results show that the use of Matlab in SimPowerSystems module circuit simulation of complex analysis and research, after all, a precise, direct and effective way.)

说明：  此程序能够处理流体力学中顶盖驱动流的动力学过程，并用程序形象的描述出来。(This program can handle lid-driven flow of fluid mechanics, the dynamic process, and describe the image with the program.)

说明：  Matlab擦除重绘动画——时钟演示,包含时针、分针和秒针，日期。(Matlab Erasemode redraw animation- Clock )

The Wavelet Neural Network This is simple example for using of modified Morlet neural network. Levenberg-Marquardt with numerical Jacobian calculation implemented. Easy to use with other optimization algorithem e.g GA,PSO, etc. The function "xox_lm" may be useful for other optimization problem easily. The function "xox_jacobian" may be useful for Jacobian calculation easily. The function "NN_fcn" may be used by the evolutionary based neural network. The activation function "modified Morlet" will be replaceable by others.

基于K-L展开的人脸检测matlab程序，采用K-L展开对图片主成分分析、多图训练，从而达到在复杂图片中检测人脸的功能。(KL expansion based on face detection matlab program, using KL expansion of the picture principal component analysis, multi-map training, so as to achieve a complex picture face detection function.)

说明：  双音频按键识别 背景： 打电话拨号时，每次按键会发出不同的声音，这些声音实际上是由一些固定频率的正弦信号合成的。因为每个按键声音包含两个不同频率的正弦信号，因此也被称为“双音频”信号，简记为DTMF。这相当于是对不同键位用‘音频’进行了编码，如同计算机领域中用数字0和1对处理对象（包括键盘）进行编码。(Two-tone buttons identify Background: When you call dial, each key emits different sounds, which is actually made up of some fixed frequency sinusoidal signal synthesis. Because the sound of each key contains two sinusoidal signals of different frequencies, it is also known as &quot two-tone&quot signal, abbreviated as DTMF. This is equivalent to different keys using the ' audio' encoded, as the computer industry with the numbers 0 and 1 pair of processing object (including the keyboard) to be encoded.)

a simple code for make a diffrent a color histograms.....enjoyyyy

这是一个Noiselet变换的程序，应该会比较有用，有兴趣的可以到MGA网站查看其具体应用。(This is a Noiselet transformation process, should be more useful, interested can go to the MGA Web site to view their specific applications.)

MTI，LFM脉冲串信号，对多目标回波进行脉冲压缩，再进行MTI。(MTI, LFM pulse train signal, multi-target echo pulse compression, then MTI.)
