cma算法的源代码,可仿真出图，还是不错的(cma algorithm source code, can be a simulation diagram, or good)

FIR(Finite Impulse Response)滤波器：有限长单位冲激响应滤波器，是数字信号处理系统中最基本的元件，它可以在保证任意幅频特性的同时具有严格的线性相频特性，同时其单位抽样响应是有限长的，因而滤波器是稳定的系统。因此，FIR滤波器在通信、图像处理、模式识别等领域都有着广泛的应用。 (FIR (Finite Impulse Response) filters: finite impulse response filter unit, digital signal processing system is the most basic components, it can ensure that any increase in the frequency characteristics of both a strictly linear phase frequency characteristics, while its unit sample response is finite, and therefore the system filter is stable. Therefore, FIR filters in communications, image processing, pattern recognition and other fields have a wide range of applications.)

说明：  时域有限差分法在matlab环境下进行的仿真，更形象地说明了时域有限差分法(FDTD method in matlab simulation environment, but also vividly describes the FDTD method)

实现图像的像素放大功能，插值放大法,例如将一副128*128的图像放大为512*512的图像，希望对大家有所帮助(Image pixel zoom function, interpolation magnify)

该源码工具包能实现矩阵的NMF分解，即矩阵的非负分解，能够用于图形的处理(This code can be used to realize NMF facterization of matrix)
