Design Patterns: Functions
Lecture Week 9
Design Patterns
We have learnt a number of patterns that we reuse
One way to reuse them is to look them up in our old
code, or notes, and then copy/paste them into our
new
A better way is to use Mfiles
We want t

Simple Loop

i = 1;

block of code
i = 2;
end

The challenge in writing FOR
loops is to figure out a single
block of code, which on every
iteration will result in the desired
Motion and Conditionals (If)
Lecture Week 5
MOTION
Put shapes on the figure
Then you can
Make small changes between frames
move them
change them
recolor them.
Time can be 1/20th 1/50th of a second
For appearance of continuity
