这个文档是教DSP应用工程师在仿真的时候如何准确的掌握程序运行的时间，当程序遇到问题对检查错误有帮助(This document is to teach DSP application engineers in the simulation, when an accurate grasp of how to run the time, when the program encountered a problem and help check for errors on)

根据系统的阶跃响应，计算时域性能指标（比如超调量、峰值、调节时间等）。(According to the step response of the system, calculate the time-domain performance indicators (such as overshoot, peak, adjust the time).)

This is the Source code for MATLAB DWT watermarking.

说明：  This code is related to the course Digital Communications. It makes a simple communication system which uses AWGN and QPSK

说明：  该程序通过雅可比矩阵求解Lorenz系统的李雅普诺夫指数指数。(The program solves Lyapunov exponent of Lorenz system by Jacobian matrix.)

BP神经网络函数拟合源程序,可实现BP网络的算法拟合(BP neural network function fitting source, can be achieved BP network algorithm for fitting)

Openness is the property of distributed systems such that each subsystem is continually open to interaction with other systems (see references).
