《matlab实例》有关ctrllab3.1方面的实例源码，希望对大家有帮助。(" Matlab example of" about ctrllab3.1 Examples source code, we want to help.)

Calculates normals of a mesh. A mesh is without normals if it is constructed using pointCloud2rawMesh.m or is read from a ply or vrml file.

说明：  LFM雷达信号处理，FFT信号处理，脉冲积累。(LFM radar signal processing, FFT signal processing, pulse accumulation.)

permutar matriz y generador de arreglo de numeros aleatorios irrepetibles

功能：用BFGS算法求解无约束问题：min f(x) 输入：x0是初始点，fun,gfun分别是目标函数及其梯度； varargin是输入可变参数变量，简单调用bfgs时可以忽略它， 但是其他程序循环调用时将会发挥重要作用 输出：x,val分别是近似最优点和最优值，k是迭代次数。(Function: BFGS algorithm for unconstrained problem: min f (x) Input: X0 is the initial point, fun, gfun each objective function and its gradient varargin variable parameter is the input variable, it can be ignored when a simple call bfgs , but other programs will play an important role when the cycle is called output: x, val are approximate optimum and the optimal value, k is the number of iterations.)

This program apply downsampling on a speech file.
