基于matlab对灰度图像的二值化自适应阈值的算法(Gray image binarization adaptive algorithm)

这是个cofdm的仿真程序，可以运行，界面较好，可以看到各个过程的数据变化(This is a simulation program, can cofdm operation, interface is good, can see various process data changes)

根据不同的地理位置转化坐标的matlab源程序，给出注释，方便修改。(Depending on the geographic coordinate transformation matlab source, give comments, easy to modify.)

一阶倒立摆，GUI仿真，源程序说明，模型制作方法及图片(First order inverted pendulum, GUI simulation, source program, model making methods and pictures.)

这是龚纯《精通MATLAB最优化计算》随书源码(M文件)。基于MATLAB优化工具箱，代码包含的内容有：牛顿法等无约束一维极值问题、单纯形搜索法等无约束多维极值问题、Rosen梯度投影法等约束优化问题、L-M法等非线性最小二乘优化问题、线性规划、整数规划、二次规划、粒子群优化、遗传算法。(This is pure Gong " Mastering MATLAB optimization calculations," with the book source (M file). Based on MATLAB Optimization Toolbox, the content code contains: Newton and other non-binding one-dimensional extremum problems, such as simplex search method for unconstrained multi-dimensional extremum problems, Rosen gradient projection method and other constrained optimization problems, LM non-linear law least squares optimization problem, linear programming, integer programming, quadratic programming, particle swarm optimization, genetic algorithm.)

圆周卷积 的matlab实现法。对matlab新手适用。(Circular convolution in matlab implementation method. On the matlab novice apply.)

对几个混合的常规信号进行傅里叶变换，并将其分离开。然后对几个信号进行时频分析，并求出参数估计的误差。(Conventional signals of several mixed Fourier transform, and separated them. And then the several signal time-frequency analysis, and the parameter estimation error.)

深度有向寻圈。访问当前某个顶点的后继，再访问后继的某个子顶点，若没有，返回上一层访问其他后继(Depth of the search circle. The current follow-up visit to a vertex, then visit a subsequent sub-vertex, if not, return to the level of other follow-up visit)

These are some basic matlab codes.
