Welcome to Laplace Academy
Today we are going to learn how to deal with polynomials in MATLAB.

Lots of stuff are covered in this tutorial, Some of them are:
Defining a polynomial as a function in MATLAB
Defining a polynomial as a symbolic expression
Addition and subtraction of polynomials
MATLAB polynomials multiplication
MATLAB polynomials division
Fitting a polynomial to data points
Introducing MATLAB basic fitting
MATLAB curve fitting toolbox

These are the functions discussed:
roots
polyval
conv
deconv
polyder
sym2poly
poly2sym
polyfit
