对于Matlab中simulink模块仿真进行了详尽的说明 主要用途集中在控制系统仿真上(This is a introduction of simulation of dynamic system based on the simulink module. This article focus on the control system.)

MATLAB LAB MANUAL PROGRAM OF SIGNAL PROCESSING

本书介绍了matlab在控制系统中的使用，涉及matlab的基本操作及系统的频谱分析、状态空间分析等内容(This book describes the matlab use in the control system, the content spectrum analysis involves matlab basic operations and systems, state space analysis, etc.)

基于均方误差参数比较OFDM系统中LS和MMSE两种自适应信道估计算法的性能，程序开头都有英文注释，可以直接运行的~个人认为写得比较好，跟大家一起分享~(Based on the Mean Square Error Comparison of OFDM system parameters LS and MMSE channel estimation of two adaptive algorithms, procedures are available in English at the beginning of the Notes, you can directly run the ~ personally think that is better written, with the U.S. to share ~)

黄金分割法，附带说明，程序可直接运行,,有实例说明，是数值最优化方面的(Golden section method, with instructions, the program can be run directly)

fit_maxwell_pdf - Non Linear Least Squares fit of the maxwellian distribution. given the samples of the histogram of the samples, finds the distribution parameter that fits the histogram samples. fits data to the probability of the form: p(r) = sqrt(2/pi)*(a^(-3/2))*(r^2)*exp(-(r^2)/(2*a)) with parameter: a format: result = fit_maxwell_pdf( x,y,W,hAx ) input: y - vector, samples of the histogram to be fitted x - vector, position of the samples of the histogram (i.e. y = f(x,a)) W - matrix or scalar, a square weighting matrix of the size NxN where N = length(y), or 0 to indicate no weighting is needed. hAx - handle of an axis, on which the fitted distribution is plotted if h is given empty, a figure is created. output: result - structure with the fields a - fitted parameter VAR - variance of the estimation type- weighted LS or not weighted LS iter- number of iteration for the solution
