Adding fields of two different structs together

% Example structures:

part(1) = struct('name', 'x', 'number', 1);

part(2) = struct('name', 'y', 'number', 2);

part(3) = struct('name', 'z', 'number', 3);

% Example: 1st user input should be the 'name' so "x"

% 2nd user input should be another'name' so "z"

% total_number = 1 + 3

part(1) = struct('name', 'x', 'number', 1)

part = struct with fields:
      name: 'x'
    number: 1

part(2) = struct('name', 'y', 'number', 2); 
part(3) = struct('name', 'z', 'number', 3); 
part(1).number+part(3).number

ans = 4

Thanks for the response but is there a way to make it depend on the user's input?

For example I would like the user to input two names, say 'y' and 'z', and then come up with the sum of numbers

" is there a way to make it depend on the user's input?"

part = struct("x",1,"y",2,"z",3);
part.("x")+part.("z")

ans = 4

It would be a better to use a dictionary than a struct,

part=dictionary(["x","y","z"],1:3);

part("x")+part("z")

ans = 4

oh ok thank you!
