基于GUI的均衡器设计，想做均衡器的同学可以借鉴一下哈~~(GUI-based equalizer design)

使用matlab来实现图像去噪功能，图像可以随机确定。(Using matlab to realize the function of image denoising, image can be determined randomly.)

In order to minimize power losses caused by high current and improve the voltage profile in the network distribution, the introduction of dispersed generations also called productions decentralized in distribution network (DG) plays an important role. The installation of DGs directly affects the power requested or purchased. The sizing and placement of DGs in the system must be optimal because a wrong choice has a negative impact on the system behavior. To solve this combinatorial problem, an algorithm known as Firefly algorithm is proposed in this paper. This is a meta-heuristic algorithm inspired by the behavior of fireflies flashing. The main objective of firefly flash is to act as a signaling system to attract other fireflies. Networks tested IEEE69-bus and IEEE33-bus are used to evaluate the effectiveness of this method. The results are compared with those obtained by genetic algorithm (GA) to IEEE69-bus, and Shuffled frog leaping algorithm (SFLA) for IEEE 33-bus.

这里面的是matlab代码，能够实现图像的分割和特征的提取，很实用(There is a matlab code to achieve segmentation and feature extraction of image，Very practical)

在原有matlab程序的基础上增加一个功能即原有程序在未统计之前，一个数默认频次为一，但是这个可以在频次不为1的情况下统计总的频次(Add a function on the basis of the original matlab program that is not before the original program statistics, a number of default frequency is one, but this can count the total frequency in the frequency is not a case)

利用最小二乘法实现手写体数字识别，采用mnist数据集(simple program using least-square)

基于MATLAB的电力系统潮流计算模块 (MATLAB-based Power Flow Calculation of Power System Module)
