在matlab环境下的系统小波的电力系统谐波分析的M程序(In the matlab environment system of the wavelet power system harmonic analysis M program)

In this File, performance evaluation of 4-QAM system in the presence of Automatic Gain Control (AGC) errors using MATLAB Software. The system is designed, modeled and simulated using Simulink to evaluate the Bit Error Rate (BER) of the system in AWGN channel. The system doesn’t have a perfect AGC, but for comparison purposes, the perfect AGC is also included and evaluated.

说明：  图像压缩：对图像进行压缩，取得了比较好的压缩效果。(image compression：compress the image and get a good compression results.)

读写ply文件的matlab实现。Writes a mesh to a ply file and Reads a ply file (text format). ply files can be in binary format as well(Writes a mesh to a ply file (text format) wich can be read by PlyView from Cyberware and Scanalyze from Stanford University. Both are available for free. Reads a ply file (text format). ply files can be in binary format as well this function can read ply files in txt format only e.g. created by makePly.m.)
