% function output = poly(x)

% output = 1234*x.^3-43388*x.^2+531*x-123;

% end

% now we can solve lengthy and complicated polynomials quickly
poly(45)

% this extends to using matrices as well
poly([1 2; 3 4])

% example usage of input()
a = input('Enter the value for a: ')

% Jupyter notebook doesnt allow for user input

% the result in a MATLAB command window is:
% Enter the value for a: 4

% a =
%     4

% providing matrices will also work

% we can also read strings 
Name = input('What is your name: ','s')

% Here is the code for calculating area of triangle with user input 
b = input('Enter the value for the base: ');
h = input('Enter the value for the height: ');
area = 0.5 * b * h;
disp(['The value for area is: ' num2str(area)])
