matlab 风力机模型，简单实用。可以下来看看(matlab wind turbine modele ，useful)

matlab实现主成分分析的运算实例 简单易懂 有注释说明(Matlab implementation of principal component analysis of the operation example is simple and easy to understand)

包含了数值计算的绝大部分程序，依照英文可以查找级程序(Contains most of the numerical calculation procedure can find level program in accordance with English)

passion方程的第一类边界条件的数值解，边界条件过于复杂而无法求得解析解。这就需要借助于数值法来求电磁场的数值解。有限差分法便是一种比较容易的数值解法。(Numerical Solution of the first boundary condition passion equations and boundary conditions are too complex to be obtained by analytical solution. This requires the help of numerical methods to find numerical solution of electromagnetic fields. Finite difference method is a relatively easy numerical method.)

利用MATLAB分帧读取avi视频文件，并播放视频文件。附视频文件(Use MATLAB to read sub-frame avi video files and audio-video files. Attached to video files)

1. 判断闰年 根据输入的具体年份（在1900-2100之间，要求对输入进行有效性检查），判断是否闰年，并给出相应的提示信息 (1. To determine leap year according to input a specific year (in 1900-2100 between the call for input validation), to determine whether a leap year, and gives the corresponding tips)

光伏电池simulink仿真模型，光伏电池IV和PV特性(Simulink simulation model of the photovoltaic cells, photovoltaic cells IV and PV characteristics)

QPSK在加性高斯白噪声环境下，信噪比和误码率的仿真。 先产生一个四组符号的序列，再将该序列映射到对应的相位上。用相应的函数产生均值为零、方差为δ2的加性高斯噪声。 (QPSK the additive white Gaussian noise environment, and the signal-to-noise ratio of the simulation. First group have a four symbols of sequence, then this sequence mapped to the corresponding phase on. With the corresponding function have zero mean and variance of 未2 additive white Gaussian noise.)

利用MATLAB软件，通过编程来计算计算卫星坐标，通过输入相关参数之后就可以给出卫星的坐标(Using MATLAB software, programmed to calculate the coordinates of the satellite is calculated by the following input parameters can be given the coordinates of the satellite)
