Specify nature/type of property

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

[Wan Ji]

And then

classdef meals
properties
    food food
    colour string
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
