arnold cat 映射实验，观察其迭代次数与置乱效果的关系，这是图像加密的典型算法(arnold cat mapping experiments to observe the number of iterations and the scrambling effect relationship, which is a typical image encryption algorithm)

大地电磁二维正演程序是电磁法的基础编程，首先设置地电断面然后通过正演模拟电磁场在大地中的传播形式来得到地下地质体的电阻率情况，从而得到地下地质体情况(Two-dimensional magnetotelluric forward modeling procedure is based programming electromagnetic method, first set the geoelectric section and then through the forward modeling electromagnetic propagation in the earth in the form to get the subsurface resistivity body condition, resulting in underground geological conditions)

this is other mass-spring project with matlab gui that get initial values an d solve the motion equation and show wave of the motion

说明：  采用区域生长法和门限法对头像进行分割，程序中代码全由自己编写，直接运行main函数即可(A regional growth method and the threshold segmentation method picture, the program code is written entirely by themselves, can be directly run the main function)

dcsk差分混沌相移键控 混沌调制解调 混沌信号生成 高斯噪声(dcsk chaos modulation awgn)

压缩感知实现阵列信号处理 对比MUSIC方法(Compressed sensing array signal processing to achieve contrast MUSIC algorithm )

用实验方法测试RLC串联谐振电路的幅频特性曲线。当正弦交流信号的频率f改变时，电路的感抗、容抗随之而变.取电路电压U0作为响应，当输入电压Ui幅值维持不变时，在不同信号频率的激励下，测出U0之值，用LabVIEW程序完成频谱分析和滤波，变换等信号处理，即可测出RLC串联电路的谐振频率，(Amplitude-frequency characteristics experimentally tested RLC series resonant circuit curve. When changing the frequency f of the sinusoidal AC signal, the circuit inductance, capacitance change with Take circuit voltage U0 as a response when the amplitude of the input voltage Ui unchanged, signals at different excitation frequencies, the measured value U0, the process is complete spectrum analysis using LabVIEW and filtering, transform signal processing, can be measured RLC series circuit resonant frequency,)
