Arbitrary precision complex ball matrices using Arb¶
AUTHORS:
- Clemens Heuberger (2014-10-25): Initial version.
This is a rudimentary binding to the Arb library; it may be useful to refer to its documentation for more details.
TESTS:
sage: mat = matrix(CBF, 2, 2, range(4))
sage: x = polygen(QQ)
sage: pol = x^3 + 2
sage: pol(mat)
[8.000000000000000 11.00000000000000]
[22.00000000000000 41.00000000000000]

¶ Bases:
sage.matrix.matrix_dense.Matrix_dense
Matrix over a complex ball field. Implemented using the
acb_mat
type of the Arb library.EXAMPLES:
sage: MatrixSpace(CBF, 3)(2) [2.000000000000000 0 0] [ 0 2.000000000000000 0] [ 0 0 2.000000000000000] sage: matrix(CBF, 1, 3, [1, 2, -3]) [ 1.000000000000000 2.000000000000000 -3.000000000000000]
