Math::Symbolic::CustomUserfContributed PMath::Symbolic::Custom::DefaultMods(3)NAMEMath::Symbolic::Custom::DefaultMods - Default Math::Symbolic
transformations
SYNOPSIS
use Math::Symbolic;
DESCRIPTION
This is a class of default transformations for Math::Symbolic trees.
Likewise, Math::Symbolic::Custom::DefaultTests defines default tree
testing routines. For details on how the custom method delegation
model works, please have a look at the Math::Symbolic::Custom and
Math::Symbolic::Custom::Base classes.
EXPORT
Please see the docs for Math::Symbolic::Custom::Base for details, but
you should not try to use the standard Exporter semantics with this
class.
SUBROUTINESapply_derivatives()
Never modifies the tree in-place, but returns a modified copy of the
original tree instead.
Applied to variables and constants, this method just clones.
Applied to operators and if the operator is a derivative, this applies
the derivative to the derivative's first operand.
Regardless what kind of operator this is called on, apply_derivatives
will be applied recursively on its operands.
If the first parameter to this function is an integer, at maximum that
number of derivatives are applied (from top down the tree if possible).
apply_constant_fold()
Does not modify the tree in-place by default, but returns a modified
copy of the original tree instead. If the first argument is true, the
tree will not be cloned. If it is false or not existant, the tree will
be cloned.
Applied to variables and constants, this method just clones.
Applied to operators, all tree segments that contain constants and
operators only will be replaced with Constant objects.
mod_add_constant
Given a constant (object or number) as argument, this method tries hard
to fold it into an existing constant of the object this is called on is
already a sum or a difference.
Basically, this is the same as "$tree + $constant" but does some
simplification.
mod_multiply_constant
Given a constant (object or number) as argument, this method tries hard
to fold it into an existing constant of the object this is called on is
already a product or a division.
Basically, this is the same as "$tree * $constant" but does some
simplification.
