matlab程序设计与应用，主要是简单的偏微分方程及画图讲解(matlab program design and application, mainly simple partial differential equations and drawing on)

线性调频信号的灵巧噪声卷积干扰matlab实现(Chirp signal dexterity the noise convolution interference matlab achieved)

图像合成 内容：随意选择两个图像，选择其中一张图像中的部分内容，利用 matlab 编程添加到另一张图像中；所有的代码添加了注释(the choice of two images, choose one of parts of the image, by using matlab Programming is added to another in the image All of the code to add comments )

用Canny算子检测图像的边缘 P0404：图像的阈值分割 P0405：用水线阈值法分割图像 P0406：对矩阵进行四叉树分解 P0407：将图像分为文字和非文字的两个类别 P0408：形态学梯度检测二值图像的边缘 P0409：形态学实例——从PCB图像中删除所有电流线，仅保留芯片对象(with Canny operator to detect the edges in the image P0404 : image thresholding segmentation P0405 : water line threshold method image segmentation P0406 : matrix Quadtree P0407 : images into text and non-text of the two categories P0408 : morphological gradient detection Binary Image Edge P0409 : morphology example-- Images from the PCB to delete all current lines, retaining only chip targets)

Fit calculates coefficients c of the least-squares approximating polynomial

A fourier filter for time-series signals. Does not require the Signal Processing Toolbox. There is an interactive version with sliders that allow you to adjust the filter parameters continuously while observing the effect on your signal dynamically.
