Tasks:
1. Question statement :
Make a GUI for a converter that takes a distance value in an Edit box
and outputs the result in another Edit box. The GUI will have buttons
to convert the entered value to the desired value. 1 kilometer = .621
miles, 1 mile = 1.61 kilometers
Solution:
var1=get(handles.edit1,'String');
to_mile=str2double(var1)*0.62;
set(handles.edit1,'String',num2str(to_mile));
var2=get(handles.edit1,'String');
to_kilo=str2double(var2)/0.62;
set(handles.edit1,'String',num2str(to_kilo));

2. Question statement:
Create a GUI for a simple calculator that can perform the following
operations: • Addition • Multiplication • Division • Subtraction All
these functions are mapped to different buttons and the entered values
are in different Edit Boxes.
Solution:
Changes in code of GUI :
Function for subtraction :
var4=get(handles.edit1,'String');
var5=get(handles.edit2,'String');
subtraction=str2double(var4)-str2double(var5);
set(handles.edit4,'String',num2str(subtraction));
Function for addition:
var3=get(handles.edit1,'String');
var4=get(handles.edit2,'String');
addition=str2double(var3)+str2double(var4);
set(handles.edit4,'String',num2str(addition));
Function for division :
var5=get(handles.edit1,'String');
var6=get(handles.edit2,'String');
division=str2double(var5)/str2double(var6);
set(handles.edit4,'String',num2str(division));
Function for multiplication:
var8=get(handles.edit1,'String');
var7=get(handles.edit2,'String');
multiplication=str2double(var8)*str2double(var7);
set(handles.edit4,'String',num2str(multiplication));

3. Question statement:
Modify Task 2 to make the calculator a scientific one. You can add
functions like sin, tan, cos, square root etc. Add as many functions as
you like to this calculator.
Solution:
Function for sin :
var7=get(handles.edit1,'String');
sin_of_var=sin(str2double(var7));
set(handles.edit1,'String',num2str(sin_of_var));
Function for cos:
var7=get(handles.edit1,'String');
cos_of_var=cos(str2double(var7));
set(handles.edit1,'String',num2str(cos_of_var));
Function for tan :
var7=get(handles.edit1,'String');
tan_of_var=tan(str2double(var7));
set(handles.edit1,'String',num2str(tan_of_var));
Function for mod:
var7=get(handles.edit1,'String');
tan_of_var=tan(str2double(var7));
set(handles.edit1,'String',num2str(tan_of_var));
