在matlab中仿真OFDM的源代码：）(OFDM simulation in matlab source code:))

Implement and investigate into stochastic Galerkin methods with a special focus on tensor product methods.

说明：  求解非线性方程组，迭代法，数值分析，不动点迭代法(Solving nonlinear equations)

用matab写的一些源程序，对学习matlab的初学者比较有用！(Matab written by some source of learning more useful for beginners in matlab!)

原始snake matlab 源碼，簡單版( seg = localized_seg(I,init_mask,max_its,rad,alpha,method) Inputs: I 2D image init_mask Initialization (1 = foreground, 0 = bg) max_its Number of iterations to run segmentation for rad (optional) Localization Radius (in pixels) smaller = more local, bigger = more global alpha (optional) Weight of smoothing term higer = smoother method (optional) selects localized energy 1 = Chan-Vese Energy 2 = Yezzi Energy (usually works better))

来自国外的2D phase unwrap 的matlab源码。基于branch cut(剪枝法) 及FloodFill（洪泛法）实现。速度很快。相位解卷绕精度高。(2D phase unwrap from abroad matlab source. Based branch cut (Pruning) and FloodFill (flooding method). Fast. Phase unwrapping high precision.)

已采集线性震动系统（钢板）的输入与输出（时域幅值），求解系统数值解，幅频特征，并作图比较。(Have been collected linear vibration system (steel) input and output (time domain amplitude), numerical solution for solving the system, the amplitude-frequency characteristics, and mapping to compare.)

在毕设过程中，网上搜集来的基于matlab多点约束的波束形成算法，自己做了改进和注释(capon beamforming，multipoint restriction)

说明：  this file is about ind FOC control.

最速下降法的Matlab程序，实现函数无约束条件下的最小值求解(Steepest descent method in Matlab, functions to achieve the minimum under no constraints to solve)
