_fmpq_vec_init n

Initialises a vector of fmpq values of length \(n\) and sets all values to 0. This is equivalent to generating a fmpz vector of length \(2n\) with _fmpz_vec_init and setting all denominators to 1.

_fmpq_vec_clear vec n

Frees an fmpq vector.

_fmpq_vec_randtest f state len bits

Sets the entries of a vector of the given length to random rationals with numerator and denominator having up to the given number of bits per entry.

_fmpq_vec_randtest_uniq_sorted vec state len bits

Sets the entries of a vector of the given length to random distinct rationals with numerator and denominator having up to the given number of bits per entry. The entries in the vector are sorted.

_fmpq_vec_sort vec len

Sorts the entries of (vec, len).

_fmpq_vec_set_fmpz_vec res vec len

Sets (res, len) to (vec, len).

_fmpq_vec_get_fmpz_vec_fmpz num den a len

Find a common denominator den of the entries of a and set (num, len) to the corresponding numerators.

_fmpq_vec_dot res vec1 vec2 len

Sets res to the dot product of the vectors (vec1, len) and (vec2, len).

_fmpq_vec_fprint file vec len

Prints the vector of given length to the stream file. The format is the length followed by two spaces, then a space separated list of coefficients. If the length is zero, only \(0\) is printed.

In case of success, returns a positive value. In case of failure, returns a non-positive value.

_fmpq_vec_print vec len

Prints the vector of given length to stdout.
