matlab在高等数学、线性代数、符号运算、图形图像处理、数据处理等方面的应用和外部借口程序设计。(matlab in advanced mathematics, linear algebra, symbolic computation, graphics, image processing, data processing applications and external under the pretext of program design.)

高斯消去法，用Matlab实现的。显然没有matlab自带的算法好，所以是练习以及和其他算法比较用的。(Gaussian elimination method, implemented with Matlab. Obviously there is no algorithm matlab own good, so is the practice and compare with other algorithms used.)

MATPOWER 一款基于MATLAB的电力系统潮流计算及优化的程序，很好很强大(MATPOWER a MATLAB-based Power Flow Calculation and optimization of procedures, very very powerful)

FastCSMatrix: The operator form of the contraint matrix for the fast compressed sensing problem. Specifically, it returns y = A*x (mode = 1) or y = A *x (mode = 2), where A is an mxn matrix given by A = [Phi - Phi], and Phi = P*H*Q, where P,Q are random permutation matrices, and H is a fast Hadamard/Fourier operator.

说明：  通信信号的调制信息包含在信号的瞬时幅度、相位、频率的变化之中，不同的信号其频谱也呈现不同的特征，通过提取瞬时幅度、相位、频率以及频谱的参数统计特征，可以识别不同的通信信号。通常是利用对瞬时幅度、瞬时相位，瞬时频率和信号功率谱进行某种变换而得到可以明显区分各种信号的特征参数。(Communication signal modulation information is contained in the signal instantaneous amplitude, phase, frequency changes, the spectrum of different signals also show different characteristics, by extracting the instantaneous amplitude, phase, frequency and statistical characteristics of the parameters of the spectrum, you can identify different communication signals. Usually by the use of instantaneous amplitude, instantaneous phase, instantaneous frequency and signal power spectrum a transformation which can be clearly distinguished by the characteristic parameters of various signals.)

说明：  不同信噪比下ofdm系统的仿真程序，不同的误码率(OFDM systems under different signal to noise ratio of the simulation program, different BER)
