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) = [];
