标准大气子程序，通过插值获得h=0-21336m高度大气密度，声速，静压，粘性等数据。(The standard atmospheric subroutines, h = 0-21336m highly atmospheric density, sound velocity, static pressure, viscosity data obtained by interpolation.)

采用的是RD算法实现合成孔径雷达成像，距离－多普勒RDA二维成像仿真(RD algorithm is used in synthetic aperture radar imaging, range- Doppler two-dimensional imaging simulation RDA)

使用principal component analysis PCA减少特征数目(Use principal component analysis (PCA) to reduce the number features.)

用Matlab软件搭出来的光伏电池模型，通过输入光照、温度、电压参数，可以实现光伏电池的一般特性。(Take out using Matlab software model of photovoltaic cells, by entering the light, temperature, voltage parameters, you can achieve the general characteristics of photovoltaic cells.)

To introduce the Matlab computing environment to the students(powerflow)

这个matlab程序实现了牛顿插值 （Newton s Interpolation ）算法(The matlab program Interpolation Newton (Newton s Interpolation) algorithm)

一些常见的matlab源代码，参加建模的人很值得一看(Common matlab source code, it is worth a visit to participate in modeling)

压缩感知方法演示，1-D信号压缩传感的实现(正交匹配追踪法Orthogonal Matching Pursuit) 测量数M>=K*log(N/K),K是稀疏度,N信号长度,可以近乎完全重构(1-D signal is compressed sensing to achieve (orthogonal matching pursuit method Orthogonal Matching Pursuit) number of measurements M> = K* log (N/K), K is the sparsity, N signal length, can be almost completely reconstructed)

说明：  matlab实现的数字水印，经验证能够实现(matlab implementation of digital watermarking, proven to achieve)
