learning matlab software for simulations

This system models a double pendulum system where the rest state has the pendulums balanced to hang at right angles to one another.

this source code is busout matlab

this is improved prony method that is very strengs for noisy signal

利用matlab写成的窄带噪声发生，处理信号的时频分析，窗函数法设计一个数字带通FIR滤波器。( Using matlab written narrowband noise occurs, When processing a signal frequency analysis, A window function design FIR digital band-pass filter.)

没什么好东西！只是BP，PID算法而已！可以看看过得去(nothing good things! Only BP, PID algorithm! Can look at the little things)

在偏微分方程的数值求解中，有一类很重要的问题就是求解有奇异点的泊松方程，此程序是用C写的并行程序，能极大的提高泊松方程的求解(In the numerical solution of partial differential equations, there is a class of very important issues that have a singular point of solving the Poisson equation, this program is written in C parallel programs, can greatly improve the solution of the Poisson equation)

此代码展示了在mimo系统中分别用ML MMSE ZF和MMSE-SIC检测算法的不同误码率曲线(This code shows the mimo system respectively ML MMSE ZF and MMSE-SIC detection algorithm different BER curves)

说明：  课件主要讲解了周期信号，非周期信号脉冲信号的原理以及MATLAB的编程(Courseware mainly explained the periodic signals, aperiodic signals, and the principle of pulse MATLAB programming)

costas环的simulink实现，可以直接在matlab上运行实现通信系统中的载波同步，对于学习或设计通信系统有很大帮助(simulink realization of costas loop that can run directly on the matlab implementation of carrier synchronization in communications systems, communications systems for the study or design of great help)
