主要实现对图像的二维傅里叶变换，并以一种更加直观的方式显示结果。(Main realization of image 2 d Fourier transform, and in a more intuitive way to show results.)

把地心惯性坐标系中的坐标转换为经度纬度和高度(convert Geocentric inertial coordinate system to longitude latitude and altitude)

This function quickly plots raster plots of large quantities of spike train data. Inputs can be spike times or binary spike train data organized by trial. It can also plot well-formatted single spike trains.

本程序的目的是模拟一个ARMA模型，然后进行时频归并。考察归并前后模型的变化(This procedure aims to simulate an ARMA model, and then proceed to merge time-frequency. Inspected before and after the model of merging changes)

最新的电力系统分析软件包 V2.1.8，包含了：PF-潮流计算；CPF-连续潮流；OPF-最优潮流；SSSA-小扰动分析；TDS-时域仿真；GUI-用户人机界面；GNE-自定义模型等功能。经过验证，该工具包已经可以计算上千节点规模的系统。而且该软件包源代码完全公开，因此用户可以根据自己的研究兴趣编写修改相应源代码实现研究目的。(The Power System Analysis Toolbox (PSAT) is a Matlab toolbox for electric power system analysis and simulation. )

Study of the interaction between wind power plants and SMES systems

说明：  由于matlab提供了一些很有用的计算方法 但是大部分用户只用到其中一部分的功能 所以写了一个包括解方程，矩阵计算，排序功能的代码(As matlab provides some very useful method but most users only use part of the function it was a including solving equations, matrices, and sorting code)
