PSO_AI

电源-地同步噪声电磁仿真程序，用FDTD编写的，可以参考一下，终端匹配(applies finite difference time domain method to analyze transmission coefficient.)

包含了使用matlab对声音信号进行时域和频域分析，加高斯噪声，并用高通、低通、带通滤波器进行滤波，并显示波形图。(Contains the sound signal using matlab time domain and frequency domain analysis, plus Gaussian noise, and high-pass, low pass, band pass filter to filter and display waveforms.)

比较两个netcdf文件 1。通过添加内部ind2sub1函数remove函数依赖第三方 2。格式化文本(Description NCCMP compares two netcdf files and prints the differences. This function is useful for testing mathematical forecasting or prediction models. USAGE: NCCMP(ncfile1,ncfile2) NCCMP(ncfile1,ncfile2,tolerance,forceCompare) INPUT: ncfile1- name of the NetCDF file to compare ncfile2- name of the NetCDF file to compare tolerance- Compare numeric data using a tolerance threshold forceCompare- if false, exit when first difference is found true: continues to process all variables EXAMPLES: nccmp( old.nc , new.nc ,0.000001) nccmp( old.nc , new.nc ,[],true) FEATURES: 1. Print the differences and their locations 2. Exits when first difference is found or optionally continues to process all variables 3. User defined tolerance threshold to compare the variables TO DO: 1. Specific variable inclusion or exclusion 2. Specific attribute inclusion or exclusion 3. Option to ignore the history attribute 4. Ignore difference between v)

Matlab code for calculating admitance for the system

1.matlab编程，实现函数的倒排序； 2.程序实现FFT,傅立叶逆变换； 3.一个图像处理程序，添加噪声，去噪。 (1.matlab programming, realize inverted sort function 2. Procedures realize FFT, inverse Fourier transform 3. An image processing program, add noise, de-noising.)
