Detailed Description

Generates notes by searching for a chaotic dynamical system defined by a polynomial equation or partial differential equation using Julien C. Sprott's Lyupanov exponent search, or by translating a known chaotic dynamical system into music, by interpreting each iteration of the system as a note. The time of the note can be represented either as the order of iteration, or as a dimension of the attractor. See Julien C. Sprott's book "Strange Attractors".

The default implementation does nothing.

Reimplemented from csound::Node.

Reimplemented in csound::Cell, csound::Hocket, csound::MCRM, and csound::Rescale.

const [virtual, inherited]

Returns the local transformation of coordinate system.

Reimplemented in csound::Random.

virtual ublas::matrix<double> csound::Node::traverse	(	const ublas::matrix< double > &	globalCoordinates,
		Score &	score
	)			[virtual, inherited]

The default implementation postconcatenates its own local coordinate system with the global coordinates, then passes the score and the product of coordinate systems to each child, thus performing a depth-first traversal of the music graph.

Reimplemented in csound::Hocket, and csound::Sequence.
