How to extract property values from an object array and put it into a new array?

classdef Datatest

properties (SetAccess = 'public' ,GetAccess = 'public')

Name

end

end

% creating 4 objects of the class 'Datatest'

x1 = Datatest();

x2 = Datatest();

x3 = Datatest();

x4 = Datatest();

% Changing the name of each objects property

x1.Name = 'test1';

x2.Name = 'test2';

x3.Name = 'test3';

x4.Name = 'test4';

% array of objects

list = [x1 x2 x3 x4]

dropDown = zeros(1,4)

for i=1:4

dropDown(i) = list(i).Name

end

i would like to create an array called 'dropDown' and extract all the names of objects from the object list. I tried this code which is giving me an arror "Unable to perform assignment because the left and right sides have a different number of elements."

% Changing the name of each objects property
x1.Name = 'test1';
x2.Name = 'test2';
x3.Name = 'test3';
x4.Name = 'test4';
list = [x1 x2 x3 x4];

dropDown=string({list.Name})

dropDown = 1×4 string array
    "test1"    "test2"    "test3"    "test4"
