Collector for Uniform Linear Array

i wrote this code

array = phased.ULA('NumElements',2,'ElementSpacing',0.5);
collector = phased.Collector('Sensor',array,...
    'PropagationSpeed',physconst('LightSpeed'),...
    'OperatingFrequency',3e8,'Wavefront','Plane');
x =[1 -1 1 -1]';
y = collector(x,[45;0])

according to matlab example in my matlab but i got this error: Array formation and parentheses-style indexing with objects of class 'phased.Collector' is not allowed. Use objects (of class 'phased.Collector' only as scalars or use a cell array.) why?

You may be using an older release where the using the class name to do a function call is not supported yet, could you try the followoing?

y = step(collector,x,[45;0])
