这是一个很好的灰色预测小程序，学习学习。(This is a good little gray prediction procedure, learning to learn.)

用矩形窗设计线性相位FIR低通滤波器,给了源代码，已经调试过了。其中要用到一个函数myfreqz要自己编，在这也附上其代码。希望对大家有用。(Rectangular window with the design of linear phase FIR low-pass filter, to the source code, have been debug. To use a function which myfreqz to own, in that its code is also attached. Hope useful for everyone.)

The following Matlab project used for color segmentation by delta e color difference. Demo to perform very, very simple color detection in LAB color space.

Fisher Linear Discriminant for text classification

《有限单元法基础及matlab编程》一书中的源程序(The source program in the book "Finite element method and MATLAB programming")

说明：  拉普拉斯变换的反演是求解复杂线性系统的一个重要步骤 函数f（t）=INVLAP（f（s））提供了一种简单、有效和合理准确的方法来实现结果。(The inversion of Laplace transform is an important step in solving complex linear system The function f (T) = invlap (f (s)) provides a simple, effective, reasonable and accurate method to achieve the results.)

说明：  计DFT，IDFT,FFT,循环卷积，循环移位以及重叠保留法(Of DFT, IDFT, FFT, cyclic convolution, cyclic shift and overlap to retain the Law)

一个很好的学习图像处理的函数的例子程序，对于初级学习者来说，有很好的帮助，对于初学习者非常适合！(a good learning image processing function examples procedures for primary learners, good help, very suitable for early learners!)

这个是自适应卡尔曼滤波的程序，可以不用已知观测方程以及状态方程的噪声，能够在滤波时学习出(This is an adaptive Kalman filtering program that can do the known equations of state and noise measurement equation can learn while filtering out)
