Embedding of time series in a phase space.
phasespace(x) phasespace(x,y) phasespace(x,y,z)
Shows the 3D phase space trajectory of the system which is presented by the observation x. The phase vectors are a reconstruction by using the time delay method (Takens, 1981). A GUI provides to change the embedding dimension to 2D.
phasespace(x,y) or phasespace(x,y,z) uses the one-column vectors x, y (and z) as the components of the phase space trajectory. The representation is 2D (3D) only and cannot be switched to the other representation.
phasespace without any arguments calls a demo (the same as the example below).
