mathematica romberg integration programme code

利用matlab的m文件，仿真DPSK的差分相干解调法，从发送数据到接收数据，比较完整(Use matlab m files, simulation DPSK differential coherent demodulation method to send data to receive data from a relatively complete)

说明：  自动化指纹识别，操作简便，代码运行快捷。(fingerprint identity)

说明：  分别采用欧拉法、改进欧拉法和隐式梯形法解一阶非线性微分方程dx/dt=ax。(The Euler method, the improved Euler method and the implicit trapezoidal method are used to solve the first-order nonlinear differential equation dx/dt=ax respectively.)

该文件是我自编的FDTD 1D 2D 3D的入门MATLAB程序。然后包含一些贴片天线的代码。全是自编，点击可运行。(The files are the codes for FDTD coding including 1D 2D 3D using MATLAB. There are also codes for patch antenna modelling)

说明：  信号处理，音频处理系统中，演示脚本的声响混叠使用正弦信号(Demonstration Script of Audible Aliasing Using Sinusoidal Signals)

说明：  用于欠定盲源分离里面的盲信号分离问题，具有很不错的效果。(It is used for blind signal separation in underdetermined blind source separation and has a good effect)

输入一列整数，选择需要求子列的长度。在求最长子列，(Enter a list of integers, select the Child-giving the length of the column. Having failed to achieve the longest sub-columns,)

Lyapunov exponent of Lorenz equation

一个经典改进的pso算法，很适合初学的人学习。(A classic pso algorithm improved, it is suitable for beginners who learn.)
