choreo.segm.ODE.ImplicitRKTable.is_symmetric

ImplicitRKTable.is_symmetric(self, double tol=1e-12)

Returns True if the Runge-Kutta method is symmetric.

The method is inferred symmetric if its symmetry default falls under the specified tolerance tol.

Example

>>> import choreo
>>> Gauss = choreo.segm.multiprec_tables.ComputeImplicitRKTable(method="Gauss")
>>> Gauss.is_symmetric()
True
>>> Lobatto_IIIC = choreo.segm.multiprec_tables.ComputeImplicitRKTable(method="Lobatto_IIIC")
>>> Lobatto_IIIC.is_symmetric()
False
