数学优化工具箱，可以解决计算机视觉中的三角测量等困难问题。(Mathematical optimization toolbox, can be solved in computer vision, such as the triangulation problem.)

实现基于支持向量机的非线性识别，可以取得较好的效果(SVM-based nonlinear identification, achieved good results can be)

第一部分是关于wigner-ville程序的三个源函数（wigner分布、伪wigner分布、平滑伪wigner分布）；第二部分是关于差分的一阶、二阶导数的子函数、源函数及表达仿真实例，这两部分都是matlab环境下源程序。(The first part is a function of three sources wigner-ville program (wigner distribution, pseudo wigner distribution, smoothed pseudo wigner distribution) the second part is about the first difference, the second derivative of the subroutine, the source function and expression simulation examples These two parts are the source matlab environment.)

当信噪比低，小信号输入时噪音严重，在整个音域的声音明显变得浑浊不清，不知发的是什么音，严重影响音质。信噪比的大小是用有用信号功率（或电压）和噪声功率（或电压）比值的对数来表示的。(When the signal to noise ratio is low, serious small signal input noise, the sound of the entire range becomes significantly turbid, I do not know what made the sound, seriously affecting the sound quality. Size is the number of the signal to noise ratio by the ratio of desired signal power (or voltage) and the noise power (or voltage) represented.)

说明：  用双线性变换法设计一个Butterworth低通滤波器，要求其通带截止频率100Hz，阻带截止频率200Hz，通带衰减小于2dB，阻带衰减大于15 dB，采样频率为500 Hz。(Using bilinear transformation to design a Butterworth low-pass filter, requiring that their pass-band cutoff frequency 100Hz, stopband cutoff frequency 200Hz, pass-band attenuation is less than 2dB, stop-band attenuation greater than 15 dB, a sampling frequency of 500 Hz.)

Transform two case , the one case 1 is Fourier the 8X8 size and then use the mask to clear the high fitter . the second case 2 is cosine the 8X8 size and then use the mask to clear the high fitter .
