Referencing Property Values in Object Arrays

Given an object array objArray in which each object has a property PropName:

• Reference the property values of specific objects using array indexing:

objArray(ix).PropName

• Reference all values of the same property in an object array using dot notation.
  MATLAB returns a comma-separated list of property values.

objArray.PropName

• To assign the comma-separated list to a variable, enclose the right-side expression in
  brackets:

values = [objArray.PropName]

For example, given the ObjProp class:

classdef ObjProp
properties
RegProp
end
methods
function obj = ObjProp
obj.RegProp = randi(100);
end
end
end

Create an array of ObjProp objects:
