MATLAB Script for Generating User Interface Program

% Calculate_Attitude.m

% Launches GUI to load reference attitude, load GPS SNR sample data,

% calculate attitude, and generate plots

function varargout = Calculate_Attitude(varargin)

% CALCULATE_ATTITUDE M-file for Calculate_Attitude.fig

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

% singleton*.

%

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

% the existing singleton*.

%

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

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

%

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

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

% applied to the GUI before Calculate_Attitude_OpeningFcn gets called. An

% unrecognized property name or invalid value makes property application

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

%

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

% instance to run (singleton)".
