Question

Hi , I need help with a Matlab homework that calculate the GPA an CGPA.

NOTE: The GPA in the university is out of 5 not 4.

Thank you.

3. Student obtain his individual project to build an automated programming to calculate the GPA and CGPA using an interactive script. 4. Students must use at least two of the following functions (for, while, if, & switch)

Answer 1

function varargout = mygpa(varargin)

% MYGPA M-file for mygpa.fig

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

% singleton*.

%

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

% the existing singleton*.

%

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

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

%

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

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

% applied to the GUI before mygpa_OpeningFcn gets called. An

% unrecognized property name or invalid value makes property application

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

%

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

% instance to run (singleton)".
