Fitting-and-interpolation

自行设计产生两个离散序列信号，对其进行相加、乘及卷积运算。 利用filter命令求下面LTI系统的冲激响应，画出系统的零极点图，判断系统的稳定性、因果性。 绘出系统的频响曲线 (To design of two discrete sequence of signals , their sum , multiplication and convolution . Seeking the following LTI system impulse response filter command , draw system pole-zero diagram to determine the stability of the system , causality . Mapping the frequency response curve )

2ask调制，波形生成，图像生成，波形识别(2ask modulation, waveform generation, image generation, waveform recognition)

OpenTSTOOL_win，时间序列工具箱。里面包含用来编程的两个时间序列，让大家更加容易学习。(OpenTSTOOL_win, time series toolbox. Which contains two time series used to programming, easier to learn.)

基于一个字嵌入水印0和1bit,原理是将图像转换到空间域后选择系数类嵌入水印，能抗打印扫描攻击(based on a word and embedding watermark 0 1bit, the principle is to convert the image into the spatial domain selection class watermarked coefficient, )

混沌多步预测算法 可实现较为精确的多步预测 实用性较强(Chaotic multi-step prediction algorithm can achieve a more precise prediction of the multi-step practical stronger)

小波变化的一些参考资料，其中又步态序列的知识，参考可以做出提取步态周期(Wavelet transform some of the references, which gait sequence knowledge, reference can be made to extract gait cycle)

This simulation demonstrates the starting of a DC motor with automatic starter (5 hp 240V 1200 rpm) rated torque Tr = 30 N.m The starter is simulated by a speed-dependent effective armature resistance using a look-up table
