Hello,
This can be done by using the phased.HeterogeneousConformalArray object. This object replaces the Element property with an ElementSet property, along with an ElementIndices property which maps elements defined in ElementSet to the complete set of elements in the array.
Your code will become:
Element = [{element1},{element2},{element3},{element4}];
array = phased.HeterogeneousConformalArray();
array.ElementSet = Element; % define the unique elements appearing in the array
Then, to use one of each element, in the order that they appear in Element:
array.ElementIndices = [1 2 3 4];
Note that before calling step(array,...), you'll need to set the ElementPosition property to a 3-by-4 matrix of element positions.
