Method Details [hide private]

Factors(cls, *seq)
Class Method

source code 

Compute product over seq containing pairs (element, exponent).

element-s must belong to algebra, exponent-s must belong to the exponent algebra.

Log(cls, arg, base=None)
Class Method

source code 

Compute logarithm of arg in base.

Argument arg must be an element of exponent algebra and base is an element of an algebra.

Pow(cls, base, exponent)
Class Method

source code 

Compute power from base and exponent.

Argument base must be an algebra element and exponent must be an element of exponent algebra.

Terms(cls, *seq)
Class Method

source code 

Compute sum over seq containing pairs (element, coefficient).

element-s must belong to algebra, coefficient-s must belong to the coefficient algebra.

_matches(pattern, expr, repl_dict, wild_info)

source code 
call graph 
Overrides: algebra.BasicAlgebra._matches
