Basic calculator developed based on GUI to understand GUI

Basic calculator developed based on GUI to understand GUI push button and it's call back function.

matrix matlab,for loop,gaussian elimination,carl friedrich gauss (academic),computer,robot,object-oriented programming (programming language paradigm),matlab lectures,course,language,engineer,simulation,math,computer programming (professional field),robots,mechanics,matlab video lectures,matlab introduction,noamn 360 degree

 In this calculator we can do basic math operation like division, addition, multiplication and subtraction

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