Matlab GUI编程， RGB-HSV对应关系展现

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