Memory management¶
-
flint_mpfr *_mpfr_vec_init(slong len, flint_bitcnt_t prec)¶
Returns a vector of the given length of initialised
mpfr
’s with the given exact precision.
-
void _mpfr_vec_clear(flint_mpfr *vec, slong len)¶
Clears the given vector.
Arithmetic¶
-
void _mpfr_vec_zero(flint_mpfr *vec, slong len)¶
Zeros the vector
(vec, len)
.
-
void _mpfr_vec_set(flint_mpfr *vec1, const flint_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(flint_mpfr *res, const flint_mpfr *vec1, const flint_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(flint_mpfr *res, const flint_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(flint_mpfr *res, const flint_mpfr *vec, slong len, flint_bitcnt_t exp)¶
Multiplies the given vector of the given length by
2^exp
.
-
void _mpfr_vec_scalar_product(mpfr_t res, const flint_mpfr *vec1, const flint_mpfr *vec2, slong len)¶
- Sets
res
to the scalar product of(vec1, len)
with (vec2, len)
. Assumeslen > 0
.
