PGE 310 Exercise 7: While loops
While loops are another basic structure used to control the flow of operations within a MATLAB algorithm. For loops,
while loops, and if statements can be used in conjunction to handle most of the programming needed for eng

PGE 310 Exercise 6: Nested for loops and conditional statements
This exercise continues where exercise 4 left off, expanding on the use of for loops, and introducing
conditional statements (if statements). By the way, for loops are a type of what we call
Exercise 8: User-defined functions in MATLAB
MATLAB has a lot of built-in functions (sin, cos, exp, log, and hundreds more), but sometimes you need to
repeatedly evaluate a function that is not built-in, or repeat a particular process (like Newton's Metho

PGE 310 Exercise 1: Introduction to Vectors and Matrices in MATLAB
Material adapted from Meegan, et al., 2011
MATLAB variables can hold more than just a single value. A single variable name can be used to
represent a vector (list of values). A single vari
PGE 310 Exercise 4: Intro to Programming in MATLAB
This exercise walks you through some of the building blocks of programming in MATLAB: creating script
files, and writing and using for loops.
