mpfr_mat.h – matrices of MPFR floating-point numbers¶

Note

This module is deprecated, and will probably removed completely in the future.

Memory management¶

void mpfr_mat_init(mpfr_mat_t mat, slong rows, slong cols, mpfr_prec_t prec)¶: Initialises a matrix with the given number of rows and columns and the given precision for use. The precision is the exact precision of the entries.

void mpfr_mat_clear(mpfr_mat_t mat)¶: Clears the given matrix.

Basic manipulation¶

__mpfr_struct *mpfr_mat_entry(const mpfr_mat_t mat, slong i, slong j)¶: Return a reference to the entry at row $i$ and column $j$ of the given matrix. The values $i$ and $j$ must be within the bounds for the matrix. The reference can be used to either return or set the given entry.

void mpfr_mat_set(mpfr_mat_t mat1, const mpfr_mat_t mat2)¶: Set mat1 to the value of mat2.

void mpfr_mat_zero(mpfr_mat_t mat)¶: Set mat to the zero matrix.

Comparison¶

int mpfr_mat_equal(const mpfr_mat_t mat1, const mpfr_mat_t mat2)¶: Return $1$ if the two given matrices are equal, otherwise return $0$ .

Randomisation¶

void mpfr_mat_randtest(mpfr_mat_t mat, flint_rand_t state)¶: Generate a random matrix with random number of rows and columns and random entries for use in test code.

Basic arithmetic¶

void mpfr_mat_mul_classical(mpfr_mat_t C, const mpfr_mat_t A, const mpfr_mat_t B, mpfr_rnd_t rnd)¶: Set $C$ to the product of $A$ and $B$ with the given rounding mode, using the classical algorithm.
