快速泊松方程求解--MATLAB Fast Poisson Solver in a Square(Fast Poisson equation- MATLABFast Poisson Solver in a Square)

何光俞很早以前出版的Fortran源码集的程序代码部分(Ho Kwong Yu, published long ago set of Fortran source code section)

m文件为程序。最小二乘方法的介绍，从我的论文中截取一段出来，说明原理。N为数据的个数(m file for the program. Least squares method is introduced, from the interception of some of my papers out of that principle. N is the number of data)

< 精通MATLAB综合辅导与指南> 西安交通大学 李人厚 张平安 等译校 这是一本有关MATLAB的参考书，适合于使用MATLAB或正在打算使用MATLAB的读者。本书另辟蹊径可以借助或不借助MATLAB随带的文档资料让读者自学MATLAB。书中口语化的风格,使读者易于阅读。如书名所示,本书提供了读者精通MATLAB所需的工具。作为编程语言和可视化工具,MATLAB具有丰富的一系列功能,可解决工程、科学计算和数学学科中许多问题。本书的基本目的是通过向读者展示如何有效地使用这些功能来帮助读者增强工作能力。由于MATLAB交互式的性质,书中内容以举例方式来描述。在读者阅读本书的同时, 这些例子可以通过运行MATLAB而再现。()

Decompose image into subbands, denoise, and recompose again. fh = decomp_reconst(im,Nsc,Nor,block,noise,parent,covariance,optim,sig) covariance: are we considering covariance or just variance? optim: for choosing between BLS-GSM (optim = 1) and MAP-GSM (optim = 0) sig: standard deviation (scalar for uniform noise or matrix for spatially varying noise) Version using the Full steerable pyramid (2) (High pass residual splitted into orientations).
