expressions#
- class wrenfold.expressions.Variable#
Concrete expression for a symbolic variable.
- __eq__(self: wrenfold.expressions.Variable, other: wrenfold.expressions.Variable) bool #
Check for strict equality. This is not the same as mathematical equivalence.
- __hash__(self: wrenfold.expressions.Variable) int #
Compute hash.
- __init__(self: wrenfold.expressions.Variable, name: str, number_set: wrenfold.enumerations.NumberSet = <NumberSet.Unknown: 4>) None #
Construct a concrete
Variable
expression.- Parameters:
name – String name of the variable.
number_set – What numeric set to assume for this variable.
Examples
>>> from wrenfold import expressions, enumerations, sym >>> x = expressions.Variable('x', number_set=enumerations.NumberSet.RealPositive) >>> type(x) wrenfold.expressions.Variable >>> sym.cos(x.to_expression()) cos(x)
- is_identical_to(self: wrenfold.expressions.Variable, other: wrenfold.expressions.Variable) bool #
Check for strict equality. This is not the same as mathematical equivalence.
- property is_unique_variable#
True if the variable is a unique_variable.
- property name#
Name of the variable.
- property set#
Numeric set the variable belongs to.
- to_expression(self: wrenfold.expressions.Variable) wrenfold.sym.Expr #
Convert the variable back to a
wrenfold.sym.Expr
