there is some code in matlab that will provide help in the field if digital image processing.it includes the code of extracting region of interst, median filter, nearest neighbour point sampling technique, negative of an image etc. and it is done by myself because i am doing becholar of computer science.it does not include any copyrighted content.i hope it will help thoes people that required help in the field of digital image processing.

加窗处理的信号分析，矩形窗与hamming窗的比较。DTFT，DFT等(The windowing processing of signal analysis)

基于混沌的模拟退火算法，快速扩展随机生成树算法，有较好的参考价值。( Chaos-based simulated annealing algorithm, Rapid expansion of random spanning tree algorithm, There are good reference value.)

MATLAB仿真的SVG仿真，大家可以参考一下!(MATLAB simulation of SVG simulation, we can refer to!)

包含简单约束的全局优化算法，matlab版本(Contains a simple constraint global optimization algorithm, matlab version)

说明：  基于牛顿拉夫逊法的 ieee14节点配电网算例PQ分解法潮流计算,含原始数据和计算结果。(Based on the Newton Raphson method, the power flow calculation of the ieee14-node distribution network by the PQ decomposition method, including the original data and the calculation results.)

LTE系统中频率调度算法，利用该程序可以实现小区间干扰协调，非常适合初学者。(Frequency scheduling algorithm in LTE system, using the program can realize the inter cell interference coordination, very suitable for beginners.)

In sum capacity of an OFDM system is maximized by allocating each subchannel to the user with the highest channel gain over this channel and distributing power among subchannels in a water-filling manner.

Cell parameters are calculated and received power all possible transmissions are plotted

这是一个用最速下降法求解线性方程的方法，程序代码使用matlab语言。 (This is a steepest descent method for solving linear equations, program code using matlab language. )
