有关粒子群算法的源代码，matlab编写，希望对需要的朋友有用。(the PSO source code, Matlab prepared, and I hope to the needs of useful friends.)

鱼眼镜头标定程序。国外一个学校的鱼眼镜头标定。含有标定图。可以自动提取角点并相机进行校正！(Fish-eye lens calibration procedures. Abroad, a school of fish-eye lens calibration. Containing calibration map. Can automatically extract the corner point and camera correction!)

利用matlab对图片频域变换、加噪声、计算SNR PSNR，对音频进行处理包括提取高音、低音、并对其进行调制解调(Using matlab frequency domain transform of the picture, add noise to calculate the SNR PSNR of audio processing including the extraction of treble, bass, and its modulation and demodulation)

simulates Inter Cell Interference Coordination techniques

一个收藏的直流潮流计算程序，供初学者使用(DC Power Flow Program)

This program calculate the conductivity of cylindrical metal nanowire using the phonon approximation in a core-shell structure, in this code, the diameter, and the metal can be changed to simulated other metals. the calculated dispersion relation of the resistivity of a single band is saved as data file. to use the program, run g_E2.m(This program calculate the conductivity of cylindrical metal nanowire using the phonon approximation in a core-shell structure, in this code, the diameter, and the metal can be changed to simulated other metals.
