均匀介质二维声波数值模拟，采用cerjan边界条件，有公式及参考文献。带有速度模型以及雷克子波函数，解压后直接运行就可以(The homogeneous medium two-dimensional acoustic wave numerical simulation, boundary conditions of cerjan, and formulas and references. With the velocity model and the the Ricker wave function, and can run directly after decompression)

数学实验中用matlab完成的仿真实验，应用matlab的很多仿真功能(Mathematics experiment with matlab simulation experiments completed, many of the matlab simulation function)

白噪声和有色噪声的生成方法，参数可以由用户自己设定(White noise and colored noise generation method, the parameters can be set by the user)

genetic algorithm solve optimization

将示波器CSV文件在MATLAB中画成图形,并进行FFT(input the .csv file of scope into matlab)

这是我多年MATLAB编程的技巧汇总，希望对大家有用。里面包含命名规则，怎样优化程序等等。(This is my years of MATLAB programming skills summary, I hope useful for everyone. Which contains the naming rules, how to optimize procedures.)

基于matlab的 双线性 数字带通 滤波器(Matlab-based bilinear digital bandpass filter)

this code is to classify objects based on their roundness using bwboundaries, a boundary tracing routine.

返回电力系统规划中用matpower计算一次潮流后得到的雅可比矩阵.(Return to power system planning using matpower after the tide once the Jacobian matrix.)
