I want to write a class where I want to fix certain variables with some validators, like {mustBeNumeric} and {mustBePositive} but I want to specify the defualt values which can be updated later. Is there any way to do this?

Hi Sameer,

There are 2 ways to do this as follows:

1 - You can specify it by assigning a default value along with the validator itself. For example :- {mustBeNumeric} = "defaultValue". But it can only be accessed if the properties of the validators are public.

2 - The alternative way is to use the 'arguments' keyword where you can specify the default values of any validators even if the property is private. You can read more about it here:- https://www.mathworks.com/help/matlab/ref/arguments.html?s_tid=doc_ta

Hope this helps!
