Please help me with System.Nullable in Matlab .Net Interface

I am new with .NET interface in matlab. Now, I am following the topic "Pass System.Nullable Arguments" and I want to build the NetDocNullable assembly.

The provided code of this assembly was written in C#, and it needs to be converted to .m file function in matlab in order to build a NetDocNullable.dll.

However, I do not know how to convert it to matlab function.

Could anyone please help me to convert this C# code to matlab function?

Thank you so much for your help.

C# code:

using System;

namespace NetDocNullable

{

public class MyClass

{

private Nullable<double> myField = null;

public Nullable<double> GetField()

{

return myField;

}

public Nullable<double> SetField(Nullable<double> db)

{

myField = db;

return myField;

}

}

}
