Find local maxima in matlab

duffing方程的混沌判别中使用到了庞加莱截面，即多维相空间中适当选取一截面 ，此截面不与轨线相切，不包含轨线，且便于观察系统的运动特征变化.(use Poincare chaotic duffing equation discriminant, multi-dimensional phase space appropriate to select a cross-section, this section is not tangent to the trajectory does not contain the rail line, and easy motion characteristics of the observed system changes.)

通信系统UDP 接收 简短的例子 可以用作测试 (Communication system UDP receive short routine)

根据以下的平板光波导在波长为1550 nm时的折射率数据 1.作 出 不 同 波 导 芯 厚 度 d (0<d<15  m)对应的TE模式 与TM模式的色散图； 2.给出满足单模与双模传输的 波导厚度范围。 3.确定包层所需的最小厚度a 与b的值(The refractive index of the optical waveguide data at a wavelength of 1550 nm according to the following plate 1. do not make the same waveguide core thickness d (0 <d <15  m) corresponding to the TE mode And TM mode dispersion map 2. The single-mode and dual-mode transmission is given to meet the Waveguide thickness range. 3. To determine the required minimum thickness of a cladding And the value of b)

此算法为用于解反问题的lsqr算法，对Ax=b，输入矩阵A，列向量b，以及迭代步数，求得列向量x(This algorithm is used for solution of the inverse problem lsqr algorithm, Ax = b, the input matrix A, the column vector b, as well as the number of iterative steps, to seek the column vector x)
