Class Hierarchy Constructor Syntax - Include all inherited properties;

I have a class with two parents. I am after a simpler constructor method that encapsulates all the inherited properties, example;
classdef signalEcho < signal & target
properties
deltaT
end
properties (Dependent)
EchoCarrierFrequency
EchoDutyCycle
end
methods
function [thisEcho] = signalEcho(thisSignal, thisTarget, deltaT)
thisEcho = thisEcho@signal(thisSignal.CarrierFrequency, thisSignal.PulseRepFreq, thisSignal.DutyCycle);
thisEcho = thisEcho@target(thisTarget.PositionX, thisTarget.PositionY, thisTarget.Velocity, thisTarget.Heading);
if nargin == 3
thisEcho.deltaT = deltaT;
end
end
Would like to replace the constructor with;
methods
function [thisEcho] = signalEcho(thisSignal, thisTarget, deltaT)
thisEcho = thisEcho@signal(thisSignal);
thisEcho = thisEcho@target(thisTarget);
if nargin == 3
thisEcho.deltaT = deltaT;
end
end
When using the above method no inherited data is populated into the the signalEcho object.

As per the "Initialize Objects Using Multiple Superclasses" section on this documentation page try removing the output argument from your calls to the constructors for the superclasses. So instead of:
thisEcho = thisEcho@signal(thisSignal.CarrierFrequency, thisSignal.PulseRepFreq, thisSignal.DutyCycle);
use:
thisEcho@signal(thisSignal.CarrierFrequency, thisSignal.PulseRepFreq, thisSignal.DutyCycle);
