% The ; means we are stoping and starting a new row
A = [1, 2, 3; 4, 5, 6; 7, 8, 9; 10, 11, 12] % 4 X 3 matrix
% making a vector and stroing it in v
v = [1;2;3] % 3 X 1 matrix
[m,n] = size(A) % the size function returns the amoutn of rows and columns and puts them in m and n
% now you can access m and n as two different variables
% You could also store it this way

RedGhoul / Protocols.swift
Created Feb 5, 2018
WTF are Protocols ?
View Protocols.swift
protocol lifeOfABear {
var fishEatenToday: Int {get}
func eatFish()
func eatHoney()
func ClimbTree()
func sleep()
}
// now all you have to do is make sure you have variable and functions implemented

RedGhoul / Optionals.swift
Created Feb 1, 2018
WTF is an Optional ?
View Optionals.swift
var Cat:String? //<- the "?" is what just made Cat a optional
Cat = "Phil Knight"
let nowUnwrapped = Cat! //"!" <- How you can tell Swift to demand a real answer from the optional
// Swift -> what is your real name cat ?
// the technical term for this is called optional unwrapping
// Optional Binding - How you can check that your optional actually holds somthing before you start using it
