Lab 5
Nested functions & Local functions
Nested functions are functions defined within functions. They are helpful when:
- We wish to write small or temporary functions which do not merit creation of a new m-file
- When we wish to share some information b

Matrix (and array/vector) operations
We will treat a vector (mathematical name for array) of some length N as a matrix of size Nx1 (or 1xN
if necessary). So any Matrix operations we describe below apply to vectors too.

LAB 2
This lab will seem like a repetition of lab 1, but considering that most of the class is new to MATLAB,
this is necessary.
There will be a class roll at the beginning of the class, and a submission of the exercises from the class
both of which will

Representing Polynomials
A polynomial of nth degree looks like:

+.+a 2 s +a 1 s+ a0
The coefficients an, an-1, , a2, a1, a0 are the coefficients of decreasing powers of s. MATLAB has
some powerful built-in functions to work with
