主成分分析法的matlab源程序，有用这种方法处理图像的不妨一试(Principal Component Analysis of the matlab source code, useful this method may wish to deal with images of one test)

以3*3为模板在一幅灰度图像中寻找像素值大于给定阈值的所有点(To 3* 3 as the template to look at a gray image pixel value is greater than a given threshold for all points)

myfunction函数介绍两个数的相加得到最后结果，以方便其它数的相加的使用。(myfunction function describes the sum of two numbers to get the final results, to facilitate the use of the sum of other numbers.)

说明：  根据连续时间函数的采样数据，利用spline重构该连续函数，并检查重构误差。(spline interpolation )

一个简单的m序列产生函数，通过调用primpoly获得本原多项式，然后通过移位循环寄存器产生所需要的序列。自相关图形上能看到峰值旁瓣电平(PSL)和积累旁瓣电平(ISL)。(A simple code for generate m-series pseudo-random sequence based PRIMPOLY function which we get the prime polynomials first,then we get the feedback connect coefficient of the cycle shift registers which generate m-series sequency. the PSL and ISL of autocorrelate function is computed on the figure. )

双曲型方程Lax-Wendroff的差分格式程序(Matlab)，非常好的例子，具体算例，有理论分析，解题过程分析，Matlab代码，注释清晰明了，有计算结果输出和图形显示，按照Word文档说明，很快就能学会，操作简单明了，非常适合新手学习。(Lax-Wendroff hyperbolic equation difference scheme (Matlab) program, a very good example, specific examples, theoretical analysis, problem-solving process analysis, Matlab code, comments clear, with the output results and graphical display, according to the Word documentation, and soon will be able to learn, easy to understand, very suitable for beginners to learn.)

低通滤波器是容许低于截至频率的信号通过， 但高于截止频率的信号不能通过的电子滤波装置。 (low-pass filter )
