张量（三维矩阵）奇异值分解即SVD分解进行图像去噪-SVD.rar

function varargout = SVD(varargin) % SVD M-file for SVD.fig % SVD, by itself, creates a new SVD or raises the existing % singleton*. % % H = SVD returns the handle to a new SVD or the handle to % the existing singleton*. % % SVD('CALLBACK',hObject,eventData,handles,...) calls the local % function named CALLBACK in SVD.M with the given input arguments. % % SVD('Property','Value',...) creates a new SVD or raises the % existing singleton*. Starting from the left, property value pairs are % applied to the GUI before SVD_OpeningFcn gets called. An % unrecognized property name or invalid value makes property application % stop. All inputs are passed to SVD_OpeningFcn via varargin. % % *See GUI Options on GUIDE's Tools menu.
