I have a MATLAB class that has a simple overloaded `plus`

function, and I can't get it to return an object. I want the function to add each field value together and output an object of the same class, with the field values being sums of the two inputs. When I add the two objects together, I get a struct, not an object. I am new to classes and am likely doing this wrong; any help would be great.

The code is as follows:

```
classdef Molar
properties
A = 0;
B = 0;
C = 0;
end
methods
function M = Molar(val)
M.A = val;
M.B = val+1;
M.C = val+2;
end
function M = plus(M1,M2)
M.A = M1.A + M2.A;
M.B = M1.B + M2.B;
M.C = M1.C + M2.C;
end
end
end
```

When it runs and I do:

```
>> x = Molar(2)
x =
Molar with properties:
A: 2
B: 3
C: 4
>> y = Molar(3)
y =
Molar with properties:
A: 3
B: 4
C: 5
```

Then I get a `struct`

when I do the `+`

operation. How can I get this to return another `Molar`

object?

```
>> x+y
ans =
struct with fields:
A: 5
B: 7
C: 9
```

I wonder if it has to do with needing to use the constructor method differently? Any help in this regard would be appreciated.

The first parameter should be the returned value:
