内容：
地理位置拟合源码程序，程序员在编程的过程中可以参考学习使用，希望对IT程序员有用，此源码程序简单易懂、方便阅读，有很好的学习价值！

部分代码如下：

function varargout = swq(varargin)

% SWQ MATLAB App displaying water quality for a given location.

% Part of the suite of example programs for the "Deploy Anywhere" article

% posted on the "Art of MATLAB" blog at www.mathworks.com. See that article

% for details on how to build and run this app.

% SWQ, by itself, creates a new SWQ or raises the existing

% singleton*.

% H = SWQ returns the handle to a new SWQ or the handle to

% the existing singleton*.

% SWQ('CALLBACK',hObject,eventData,handles,...) calls the local

% function named CALLBACK in SWQ.M with the given input arguments.

% SWQ('Property','Value',...) creates a new SWQ or raises the

% existing singleton*. Starting from the left, property value pairs are

% applied to the GUI before swq_OpeningFcn gets called. An

% unrecognized property name or invalid value makes property application

% stop. All inputs are passed to swq_OpeningFcn via varargin.

% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one

% instance to run (singleton)".
