◆ _adjust_complexity()

def CellMLToNektar.pycml._adjust_complexity	(	self,
		old_elt,
		new_elt
	)

private

Adjust ancestor complexity because old_elt changed to new_elt.

The purpose of this method is to allow us to keep track of
what the complexity of each expression node *was* prior to PE
being performed.  Thus we cannot just re-compute complexities,
but must update values using the original complexities.  If a
variable definition is instantiated, then the complexity of
the expression containing the lookup must be adjusted to
reflect the additional expense of evaluating the defining
expression.

When this method is called, only new_elt is a child of self.

◆ simplify()

def CellMLToNektar.pycml.simplify	(	self,

Simplify these units.

Create a new <units> element representing a simplified version of
this element.  This implements the algorithm of appendix C.3.1.  It
is however slightly different, in order to allow for units
conversions rather than just preserving dimensional equivalence.

If other_units is not None, then produce a simplified version of
the product of these units and other_units.  other_units are
considered to be raised to the power of other_exponent (so a
quotient can be performed by passing other_exponent=-1).  Note that
other_exponent should have numeric type.

If other_units is a UnitsSet, then we construct a UnitsSet
containing self, and call the simplify method on that, thus
returning a UnitsSet instance.

Multiplicative factors on the original <unit> objects are
maintained on the generated references, by taking the product of
all factors from <unit> objects that contribute to the new <unit>
object.  Note that this means that we may need to retain a
reference to dimensionless with a multiplier, for example if the
quotient of centimetres by metres is taken.

Offsets are only permitted on simple units, so may not appear where
there are multiple <unit> elements.  Hence when a product of units
is taken, any offsets are discarded.
