Hello,
I am writing a class in which I have the property 'food'. The property should be composed of a string specifying the type of food and a double specifying the number of calories. How do I specify this to the property? (As an example, just as I have specified 'string' to 'colour', I want to specify something for 'food')
classdef meals
properties
food
colour string
end
end
Thank you in advance for your help!

You can define another class called food
classdef food
properties
type string
calories double
end
end

First define the food class
Then define meals class
Now run meals in the command window, we get empty class meals with two field properties: food and colour
After that, look into this empty meals named ans
And see ans.food by double click it, food type and calories are there

... or something like:
classdef meals
properties
food (1,1) struct = struct( 'type',{'wheat'}, 'calories',{123} );
colour string
end
end
>> m.food
ans =
struct with fields:
type: 'wheat'
calories: 123
