i need matlab code regrading my project in image processing

数据处理及误差分析采用了matlab软件来实现，它的界面虽然没有VB等直观简便，但其可调用的函数多，实现起来比较方便，程序中已经实现的功能有： （1）求算术平均值； （2）求残余误差（绝对误差）； （3）求标准差； （4）判断粗大误差，如果发现粗大误差,剔除粗大误差后再进行计算； （5）判断数据是否具有线性误差或者周期性误差。 (Data processing and error analysis using matlab software to achieve, its intuitive interface, while not VB so simple, but its function can be called many realize it was easier, the program has been implemented features are: (1) Find the arithmetic mean (2) Find the residual error (absolute error) (3) Find the standard deviation (4) to determine gross error, if found to gross error, calculated after excluding gross error (5) to determine whether data has linear error or Periodic error.)

给定2个点坐标，计算其连线与水平方向的夹角，夹角范围[0,2*pi](failed to translate)

it will nagative the i/p image

数值模拟轨道不平顺，可以做为轮轨激励施加到轨道和轮轨上，研究轮轨的高频振动(Numerical simulation of track irregularities, can apply for wheel-rail incentive on the rail and wheel/rail, high frequency vibration of the wheel/rail)

这个程序就是最基本的粒子群优化算法程序，用Matlab实现，非常简单。只有几十行代码。(This procedure is the most basic particle swarm optimization procedures, using Matlab implementation is very simple. Only a few dozen lines of code.)

对图像作直方图均衡化处理，列出原图像直方图与均衡后图像的直方图的对照；灰度级的转换调试(For histogram equalization of image processing, listing the original image histogram and histogram equalization contrast gray-scale conversion of debugging)
