汽车七自由度模型，很实用的simulink模型(Automotive seven degrees of freedom model, very practical simulink model)

数值积分和数值微分的相应方法，程序测试无误。(Numerical integration and numerical differentiation of the corresponding program to test and correct. )

这是基于压缩感知的MP算法，经本人验证仿真，没得问题(This is based on the the compressed sensing MP algorithm, after I verify the simulation, did not have the problem)

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

面阵中二位角度估计unitary—esprit算法估计DOA(Face two Angle in the array is used to estimate the unitary estimates-esprit DOA)

求最小PID可达方差,用于评价PID控制系统的控制系能，比最小方差控制最为评价基准更可靠(PID up to find the minimum variance control system for evaluation of PID control system can be more than the minimum variance control most reliable evaluation criteria)
