1. Basic plotting
2. ```x=11
y=-3
z= 3x + y.^2
doc plot
plot (z,x, 'o') %all points are represented by symbol o. type help plot to see all the other formatting that you can use```
3. Use ezplot() to plot sinh(x). i.e  
4. ```ezplot ('sinh (x)')
ezplot ('(e.^x)- (e.^(-x))')```
5. The script below will allow you to use various commands to fit a certain type of data.
• subplot to plot two graphs next to each other
• fplot fo curve fitting
• labelling and plotting graphs using xlabel, ylabel, gtext, grid, axis, legend
• retrieve data from a graph using ginput
• plot polar coordinates and fit polar coordinates using ezpolar
• finally use inline to make scripts faster
```%==========================================================================
% Clear up workspace! -----------------------------------------------------
clear;
%==========================================================================
x= [1:1:100]; %data
y = x.^4;
plot(x,y);
hold %holds the current plot
z= x.^5; plot(x,z) %overlays the plot of z on x
close all %close all figure windows
% creating horizontal and vertical subplots--------------------------------
%horizontal subplot
subplot(1,2,1), plot(y); % represents the number of plots and their position (x,y,position).i.e in this case shows two graph side-by side.
subplot(1,2,2), plot(z);
user_entry = input('Break Task A'); %Break point

%vertical
subplot(2,1,1), plot(y);
subplot(2,1,2), plot(z);
user_entry = input('Break Task A'); %Break point
close all %close all figure windows
% fplot-fitting set of data to form a smooth curve--------------------------------------------------------------------
fplot('[x^4, x^6]',[0:10])
user_entry = input('Break Task A');
close all

% using plot to show multiple lines.
plot (x,y,'b-',x,z, 'r-');
xlabel('x');
ylabel('y');
title('figure 1');
legend('data1', 'data2', 2);
grid on; %shows the grid
gtext('A') %slick of the mouse on the graph will paste the word A on it
user_entry = input('Break Task A');

% getting data from the graph
grid on
[xin,yin]=ginput(10); % have to click mouse 10 times and it will store x and y values in xin and yin respectively
plot(xin,yin, 'rX') % plots xin and yin with a red X
user_entry = input('Break Task A');

%using polar coordinated------------------------------------------------------
theta = [0: pi/10: pi/2];
rho = cos(theta).^2;
polar(theta, rho);
user_entry = input('Break Task A'); %Break point

%using fplot equivalent- ezpolar
ezpolar('cos(t)^2', [0,pi/2]); %equivalent of fplot
user_entry = input('Break point');```
