Member Function Documentation

void F4::MonomialArray::freeTabulatedProduct

(

)

Free the static 2D array NB_MONOMIAL.

Precondition

The static variables NB_VARIABLE must be set beforehand.

Monomial const& F4::MonomialArray::getNumMonomial

(

int

index

)

Overload the operator [].

Returns

Reference on a monomial.

uint8_t F4::MonomialArray::getNumVarlist	(	int	numMon,
		int	index
	)

Get _monomialArray[numMon]._varlist[index].

Parameters

numMon	Number of the monomial.
index	Index of a variable in varlist.

Returns

_monomialArray[numMon]._varlist[index].

int F4::MonomialArray::multNumMonomial	(	int	numMon1,
		int	numMon2
	)

Multiply two monomials, using _tabulatedProduct if possible. Prefer numMon1<numMon2.

Parameters

numMon1	Number of the first monomial.
numMon2	Number of the second monomial.

Returns

Number of the product intToMonomial[numMon1] * intToMonomial[numMon2].

Monomial const& F4::MonomialArray::operator[]

(

int

index

)

Overload the operator [].

Returns

Reference on a monomial.

void F4::MonomialArray::setMonomialArray

(

)

Modify the dynamic array _monomialArray.

Precondition

The array _nbMonomial must be set beforehand.

void F4::MonomialArray::setTabulatedProduct

(

int

degree

)

Modify the static 2D array TABULATED_PRODUCT.

Precondition

Static variables NB_VARIABLE, NB_MONOMIAL and MONOMIAL_ARRAY must be set beforehand.

Parameters

degree

Maximum degree of column monomials. The degree of row monomials is 1.
