I know that it is possible to assign the values of an array to object.property using deal(). Is it possible to do such thing for object.object.property? I am specifically working with SimulationInput objects, where the variables property of this object is itself an object and has a property named value, and I want to do something like the following:

SimIn = repmat (Simulink.SimulationInput, [NumRows, NumCols]); 
[SimIn] = SimIn.setVariable ('VariableName', 0);
SimIn.Variables.Value = Data(:);

or

[SimIn(:).Variables.Value] = deal (Data(:));

No, you would have to do it in 2 steps,

[Variables.Value] = deal (Data(:));
[SimIn(:).Variables] = deal (Variables);

If you find you need to do this frequently, however, it probably means your choice of data organization is sub-optimal for your problem. You should probably have array-valued properties, rather than an array of objects.
