.. _mpfr-vec: **mpfr_vec.h** -- vectors of MPFR floating-point numbers =============================================================================== Memory management -------------------------------------------------------------------------------- .. function:: 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. .. function:: void _mpfr_vec_clear(flint_mpfr * vec, slong len) Clears the given vector. Arithmetic -------------------------------------------------------------------------------- .. function:: void _mpfr_vec_zero(flint_mpfr * vec, slong len) Zeros the vector ``(vec, len)``. .. function:: void _mpfr_vec_set(flint_mpfr * vec1, const flint_mpfr * vec2, slong len) Copies the vector ``vec2`` of the given length into ``vec1``. No check is made to ensure ``vec1`` and ``vec2`` are different. .. function:: 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``. .. function:: 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. .. function:: 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``. .. function:: 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)``. Assumes ``len > 0``.
