I was just trying to find out how to sort by field of a structure. say I have 10 cars that are all:
Car(1).name = 'BMW 3 Series'
Car(1).type = 'Sedan'
Car(1).mpg = 30
Car(1).price = 40,000
Car(1).seats= 5
(but different of course) , how could i sort them after asking a question by, say 20mpg or over, and then take that new list and sort it by price, and so on.

E.g., to sort everything by mpg:
[~,x] = sort([Car.mpg]);
CarMpg = Car(x);
To pick off only those with certain constraints, e.g.
x = [CarMpg.mpg] >= 20;
CarMpg20 = CarMpg(x);

I would use Table instead of Struct

it would make your life sooooo much easier.
Some table workflow example:
