threshold-coding

上传的内容主要是QPSK误码率仿真，保证可以运行(From the contents of the QPSK bit error rate simulation is mainly to ensure that you can run)

说明：  （插值） 在某海域测得一些点(x,y)处的水深z由下表给出，船的吃水深度为5英尺，在矩形区域（75，200）*（-50，150）里的哪些地方船要避免进入。 ((Interpolation) measured the waters in a number of points (x, y) the Agency' s water depth z is given by the following table, the ship' s five feet depth of water in the rectangular area (75,200)* (-50,150) in where the ship to avoid.)

一本很好的教材，讲关于MATLAB-SIMULINK在仿真中的应用(A very good book, talk about simulation and application MATLAB-SIMULINK)

实现2PSK系统的matlab仿真以及误码率分析( Achieve 2PSK system matlab simulation and analysis of bit error rate )

该压缩文件是OFDM的仿真MATLAB程序，包含调制解调和性能分析，希望有帮助。(The compressed file is a MATLAB simulation of the OFDM process, including modem and performance analysis, would like to have help.)

粒子群做非线性模型的参数估计，已检测很好用(nonlinear parameter estimation)

已知离散的坐标数据，利用这些坐标点进行椭圆拟合的程序(Known coordinates of discrete data points to use these coordinates ellipse fitting procedure)

本书介绍了 统计、绘图、求微积分、解微分方程、解ODE、变换、曲线拟合、特殊函数……很多的高 数方面的应用，还附有习题和答案。(Statistics, graphics, seeking calculus of differential equations, solution of the ODE, transform, curve fitting, special functions ... a lot of high- Several areas of application, accompanied by exercises and answers.)

绘制圆形的matlab代码,图片绘制了圆形，可以通过代码参数设置改变圆形的大小，位置(To draw circular matlab code, images draw a circle, you can change the size of the circle through the code parameters set, location)

this file implements the set-up of the simulation parameters for wimax matlab simulator. can be used for communications simulations. implemented as a matlab function file. very easy to use
