MatLab Code: Develop a GUI Calculator to perform the following conversion of GPS

Question

MatLab Code:

Develop a GUI Calculator to perform the following conversion of GPS coordinates

function varargout = DMS2DD_GUI_LDA(varargin)

% DMS2DD_GUI_LDA M-file for DMS2DD_GUI_LDA.fig

% DMS2DD_GUI_LDA, by itself, creates a new DMS2DD_GUI_LDA or raises the existing

% singleton*.

%

% H = DMS2DD_GUI_LDA returns the handle to a new DMS2DD_GUI_LDA or the handle to

% the existing singleton*.

%

% DMS2DD_GUI_LDA('CALLBACK',hObject,eventData,handles,...) calls the local

% function named CALLBACK in DMS2DD_GUI_LDA.M with the given input arguments.

%

% DMS2DD_GUI_LDA('Property','Value',...) creates a new DMS2DD_GUI_LDA or raises the

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

% applied to the GUI before DMS2DD_GUI_LDA_OpeningFcn gets called. An

% unrecognized property name or invalid value makes property application

% stop. All inputs are passed to DMS2DD_GUI_LDA_OpeningFcn via varargin.

%

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

% instance to run (singleton)".
