Plot complex numbers, as well as show the magnitude of error.

多尺度Retinex代码算法，能够很好的是实现边缘锐化和对比度增强。(Multi scale Retinex code algorithm, can very good realize edge sharpening and contrast enhancement.)

压缩包是三个matlab源程序，用于产生自由空间路径损耗、对数距离路径损耗以及对数正态路径损耗。(Package is three matlab source, used to produce free space path loss, log distance path loss and lognormal path loss. )

FIR滤波器设计程序，在MATLAB环境下实现FIR数字滤波器的设计(FIR filter design procedures, the MATLAB environment realize FIR digital filter design)

this is a pso alghoritms code

4MATLAB 7.0从入门到精通随书源码 很经典的书 程序应该也很有帮助(4MATLAB 7.0 from entry to the master source code with the classic book written procedures should also be helpful)

快速傅里叶变换 可以计算并且仿真出图片等，里面包括三角变换、逆变换等。(Fast Fourier Transform And simulation can be calculated, such as a picture, which includes the triangular transform, inverse transform and so on.)

基于脉冲整形的PAPR抑制matlab源代码(matlab source code for reducing PAPR of OFDM signal with PS methed)
