  3. Review • Script files • Run a list of commands • Flow Control • If, for, while, etc

  4. Functions • All variables are local variables

  5. Example

  6. Fibonacci Sequence • Write a function that calculates the nth number in the Fibonacci Sequence

  7. My solution

  8. or

  9. or

  10. or

  11. Multiple inputs and outputs • Comments + good layout make things easier to read, correct, use and re-use.

  12. Solving Equations • Write a function that solves • For real roots, otherwise displays an error. • Also creates a plot of this function. • And displays the real roots.

  13. My Solution

  14. What is the difference between a script and a m-file?

  15. Pendulum Simulation

  16. Inputs: • Length of pendulum • Starting pendulum angle • Hints: • To start just draw the pendulum in its starting position • Use Euler rule
