Memory management¶
-
mpfr *
_mpfr_vec_init
(slong len, mp_bitcnt_t prec)¶ Returns a vector of the given length of initialised
mpfr
’s with the given exact precision.
-
void
_mpfr_vec_clear
(mpfr * vec, slong len)¶ Clears the given vector.
Arithmetic¶
-
void
_mpfr_vec_zero
(mpfr * vec, slong len)¶ Zeros the vector
(vec, len)
.
-
void
_mpfr_vec_set
(mpfr * vec1, const mpfr * vec2, slong len)¶ Copies the vector
vec2
of the given length intovec1
. No check is made to ensurevec1
andvec2
are different.
-
void
_mpfr_vec_add
(mpfr * res, const mpfr * vec1, const mpfr * vec2, slong len)¶ Adds the given vectors of the given length together and stores the result in
res
.
-
void
_mpfr_vec_scalar_mul_mpfr
(mpfr * res, const mpfr * vec, slong len, mpfr_t c)¶ Multiplies the vector with given length by the scalar \(c\) and sets
res
to the result.
-
void
_mpfr_vec_scalar_mul_2exp
(mpfr * res, const mpfr * vec, slong len, mp_bitcnt_t exp)¶ Multiplies the given vector of the given length by
2^exp
.
-
void
_mpfr_vec_scalar_product
(mpfr_t res, const mpfr * vec1, const mpfr * vec2, slong len)¶ - Sets
res
to the scalar product of(vec1, len)
with (vec2, len)
. Assumeslen > 0
.
