根据matlab的bvp4c函数的例子思想方法，求解特征值和特征函数，可以解变积分边界的问题，但是须给一个比较精确的初特征值。此为自编程序，已经标明注释。所附为bvp4c相关例子（此从matlab帮助文件节选）。(use the matlab solver bvp4c to obtain the both eigenvalues and eigenfunctions of BVPs, an exact initial eigenvalue is needed.)

说明：  一种基于角点信息和透视变换的图像镶嵌源代码(A corner-based information and perspective transformation of the image mosaic source code)

自己编的matlab厂程序。这是将局部坐标系的坐标转化为球面坐标系的坐标，非常实用。(own addendum to the Matlab plant procedures. This is the will of local coordinates into spherical coordinates, very practical.)

It explains how can we get auto color by matlab

超宽带TOA定位卡尔曼滤波定位算法matlab仿真(Ultra-wideband TOA positioning Kalman filter algorithm matlab simulation)

是Matlab图像处理的原程序代码，适合初学者使用。 (Matlab image processing is the original code, suitable for beginners.)

主要用于绘制图像、比如圆柱、矩形、圆、心等，该例子绘制了一颗被包围的红心，用于表达爱意。(Mainly used to draw the image, such as cylindrical, rectangular, round, heart, etc., which are surrounded by examples drawn a red heart for affection.)

课程设计需要运用MATLAB编程实现2ASK,2FSK,2PSK，2DPSK调制解调过程，并且输出其调制后的波形，画出频谱、功率谱密度图，并比较各种调制的误码率情况，讨论其调制效果。(Curriculum design requires the use of MATLAB programming 2ASK 2FSK, 2PSK 2DPSK modulation demodulation process and output modulated waveform, draw the spectrum, power spectrum density map and compare various modulation BER discuss its modulation effect.)

自己写的利用形态滤波方法去ECG基线漂移，附MIT-BIH心电数据库（受上传文件大小所限，只包含第124号数据供程序验证）(Written by myself, ECG baseline drift is removed by morphological filtering method, with MIT-BIH ECG database (limited by the size of uploaded files, only data No. 124 is included for program verification))

fourier拟谱方法，是一种很不错的傅里叶数学算法，希望有用(fourier pseudospectral method is a very good Fourier mathematical algorithms seek to help)
