Get index of object with a given property in an array

Is it possible to remove an entry from a vector of arrays based on a certain property?

How would I get the index of a certain person in the n the phone book example on https://de.mathworks.com/help/matlab/matlab_oop/finding-objects-having-specific-settings.html?

classdef PhoneBook < dynamicprops
   properties
      Name
      Address
      Number
   end
   methods
      function obj = PhoneBook(n,a,p)
         obj.Name = n;
         obj.Address = a;
         obj.Number = p;
      end
   end
end

We add some entries:

PB(1) = PhoneBook('Nancy Vidal','123 Washington Street','5081234567');
PB(2) = PhoneBook('Nancy Vidal','123 Main Street','5081234568');
PB(3) = PhoneBook('Nancy Wong','123 South Street','5081234569');

I would now like to remove an entry based on the value of a property:

NW = findobj(PB,'Name','Nancy Wong');  % To remove an entry, I would like to get the index and not the entry itself

For the class you defined, you can use something like this

PB(1) = PhoneBook('Nancy Vidal','123 Washington Street','5081234567');
PB(2) = PhoneBook('Nancy Vidal','123 Main Street','5081234568');
PB(3) = PhoneBook('Nancy Wong','123 South Street','5081234569');

NW = findobj(PB,'Name','Nancy Wong');
PB(PB == NW) = [];

This was exactly what I was looking for.

Thanks a lot!
