Intro for c++ from MIT

fit_ML_normal - Maximum Likelihood fit of the laplace distribution of i.i.d. samples!. Given the samples of a laplace distribution, the PDF parameter is found fits data to the probability of the form: p(x) = 1/(2*b)*exp(-abs(x-u)/b) with parameters: u,b format: result = fit_ML_laplace( x,hAx ) input: x - vector, samples with laplace distribution to be parameterized 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 u,b - fitted parameters CRB_b - Cram?r-Rao Bound for the estimator value RMS - RMS error of the estimation type - ML

三次B样条曲线、一阶二阶三阶导矢曲线。可用于绘制机器人B样条轨迹的位移、速度、加速度、加加速度曲线图(Cubic B-spline curve, a second-order third-order derivative vector curve. Can be used to draw the trajectory of the robot B-spline displacement, velocity, acceleration, jerk curve)

This code is used for find the Spectral magnitude error....and Spectral phase error....
