MATLAB

说明：  实现了pcm调制的全过程的MATLAB仿真，包括调制、A率压缩、量化、解扩、解调、信号恢复。(Modulation achieved pcm MATLAB simulation of the whole process, including the modulation, A rate of compression, quantization, despreading, demodulation and signal recovery.)

this is the matlab code for the communication

增量式PID控制算法Matlab仿真程序 设一被控对象G（s）=50/(0.125s^2+7s),用增量式PID控制算法编写仿真程序（输入分别为单位阶跃、正弦信号，采样时间为1ms，控制器输出限幅：[-5,5],仿真曲线包括系统输出及误差曲线，并加上注释、图例）。(Incremental PID control algorithm Matlab simulation program to set up a controlled object G (s) = 50/(0.125s ^ 2+7s), with incremental PID control algorithm simulation program written (unit step input, respectively, sinusoidal signal sampling time is 1ms, the controller output limiter: [-5,5], including simulation system output and error curve curves, plus notes, legend).)

double pendulum simulation in matlab

说明：  打点成功的程序段 分享一下，大家互相学习(RBI to share the success of the segment, we learn from each other)

This code is about red object track. This code is done in MATLAB.

可以对比较复杂的微分方程进行求解，比如说是二阶系数微分方程。(More complex differential equations can be solved, for example, is a second-order differential equation coefficients.)

matlab的又一本教程，内用详细，丰富。分类明确，是一本很好的工具书。(matlab another in this tutorial, which used detailed, rich. Categories clear, is a very good tool.)

全相位离散频谱校正的matlab程序，能得到多频率信号的频率，幅值，相位。(All Phase discrete spectrum correction matlab program, to get multi-frequency signal frequency, amplitude and phase.)

说明：  一个统一的求无约束优化极值函数，方法名由参数传入例如：fmins(无约束方法，一维搜索方法，目标函数，初始点，精度) (A uniform evaluation of unconstrained optimization extremal functions, methods, for example, by an argument: fmins (unconstrained one-dimensional search method, the objective function, the initial point accuracy))
