Function Documentation

maximum()

Exponent maximum	(	const Exponent *	a,
		size_t	varCount
	)

Returns the largest exponent of a.

Returns zero if varCount is zero.

Definition at line 68 of file TermExtra.cpp.

median()

Exponent median	(	const Exponent *	a,
		size_t	varCount
	)

Returns the lower median exponent of a.

Returns zero if varCount is zero.

Definition at line 25 of file TermExtra.cpp.

medianPositive()

Exponent medianPositive	(	const Exponent *	a,
		size_t	varCount
	)

Returns the lower median of the positive exponents of a.

Returns zero if all terms of a are zero.

Definition at line 35 of file TermExtra.cpp.

minimumPositive()

Exponent minimumPositive	(	const Exponent *	a,
		size_t	varCount
	)

Returns the smallest positive exponent of a.

Returns zero if all entries of a are zero.

Definition at line 55 of file TermExtra.cpp.

totalDegree()

void totalDegree	(	mpz_class &	res,
		const Exponent *	a,
		size_t	varCount
	)

Puts the sum of the entries of a into res.

res has to be an mpz_class as opposed to an Exponent since the sum could cause an overflow.
