Creation

Description

aeroAircraftEnvironment = Aero.Aircraft.Environment creates a single Aero.Aircraft.Environment object with default property values.

aeroAircraftEnvironment = Aero.Aircraft.Environment(N) creates an N-by-N matrix of Aero.Aircraft.Environment objects with default property values.

aeroAircraftEnvironment = Aero.Aircraft.Environment(M,N,P,...) or Aero.Aircraft.Environment([M N P ...]) creates an M-by-N-by-P-by-... array of Aero.Aircraft.Environment objects with default property values.

aeroAircraftEnvironment = Aero.Aircraft.Environment(size(A)) creates an Aero.Aircraft.Environment object that is the same size as A and all Aero.Aircraft.Environment objects.

aeroAircraftEnvironment = Aero.Aircraft.Environment(__,property,propertyValue) creates an array of Aero.Aircraft.Environment objects with property, propertyValue pairs applied to each of the Aero.Aircraft.Environment array objects. For a list of properties, see Properties.
