Objective-function-extremum

S-function程序编写实例,本人学习MATLAB中系统函数第一个编写的程序。运行环境：MATLAB。直接运行即可。(the programming example of S-function.)

系统的结构参数和负荷情况都已给定时，调节可利用的控制变量(如发电机输出功率、可调变压器抽头等)来找到能满足所有运行约束条件的，并使系统的某一性能指标(如发电成本或网络损耗)达到最优值下的潮流分布。(Optimal power flow(OPF) is a fundamental tool in power system planning and operation.)

最小二乘支持向量机的一个小程序，非常简单，也很耗用(Least Squares Support Vector Machines, a small program, very simple and consumption)

使用matlab编写的程序,关于目标动态跟踪的,里面有可测试的视频,可以稍微改动供自己用( the program was wrrited using matlab laguage)

航位推算代码，内含三种常见的平滑处理方法代码 内含部分数据(Dead reckoning code, containing three common smoothing method code)

通信网中图论部分PRIM算法生成最小生成树的matlab程序(Communication network center theory of some PRIM algorithm to generate minimum spanning tree of the matlab program )

基于语音信号的压缩感知重构程序 采用OMP算法对语音进行重构 包含语音的分帧程序，及omp程序，程序可正常运行。(Sensing Reconstruction program is based compressed speech signals Using OMP algorithm to reconstruct speech Framing program includes speech, and omp, programs can be run properly.)

很好的matlab测试代码 对于了解矩阵由很大的好处啊 谢谢大家 还有下载(Very good test code for matlab matrix know a lot of benefits from the U.S. also download ah thanks)
