什么数据库源码太复杂 搞不懂了码重复或已经存在(What database do not understand source code is too complex to repeat the code or already exists)

本程序设计了常用的几个坐标系的转换，从WGS—84与PZ－90坐标系的相互转换，以及空间直角坐标系与大地坐标系的转换。(This procedure has designed a number of commonly used coordinate system conversion from WGS-84 and PZ-90 coordinate system conversion, as well as the spatial Cartesian coordinate system and geodetic coordinate system conversion.)

The goal of this program is to demonstrate the construction of a huffman encoding tree. The tree is represented as a binary tree using MATLAB s built in treeplot commands. Contruction of the tree as well as the huffman code book will be described in later sections

对一帧图像进行信噪比等因素的检测，比较实用(Image on a detection signal to noise ratio and other factors, more practical)

一个效果非常理想的图像颜色变换程序％The goal of this application is to change the colors of a picture, (truecolor or grayscale, *.jpg, *.jpeg), without moving the mouse, looking at them in a slideshow.(One of the effects very good image color conversion process The goal of this application is to change the colors of a picture, (truecolor or grayscale,*. jpg,*. jpeg), without moving the mouse, looking at them in a slideshow.)

在matlab环境下，利用ode命令求解常微分方程组的学习算例(In the matlab environment, the use of the command for solving ordinary differential equations ode to learn examples)

This is my first upload which contain some stuff files from my final project.

形态学中的腐蚀和膨胀运算。首先，对图像进行低通滤波，消除细小噪声的干扰。 在滤波时，没有采用传统的中值滤波器，而是采用顺序统计滤波器ordfilt2(Erosion and dilation operation in morphology. Firstly, the image is filtered by low pass filtering to eliminate the interference of small noise. In filtering, the traditional median filter is not used, but the order statistics filter ordfilt2)

这是双馈电机空载情况下，转子侧变流器的控制电路。(This is a doubly-fed machine no-load cases, the rotor side converter control circuit.)
