sequencetools.CyclicMatrix

class abjad.tools.sequencetools.CyclicMatrix.CyclicMatrix.CyclicMatrix(*args, **kwargs)

New in version 2.0.

Abjad model of cyclic matrix.

Initialize from rows:

abjad> from abjad.tools import sequencetools

abjad> cyclic_matrix = sequencetools.CyclicMatrix([[0, 1, 2, 3], [10, 11, 12, 13], [20, 21, 22, 23]])

abjad> cyclic_matrix
CyclicMatrix(3x4)

abjad> cyclic_matrix[2]
CyclicTuple([20, 21, 22, 23])

abjad> cyclic_matrix[2][2]
22

abjad> cyclic_matrix[99]
CyclicTuple([0, 1, 2, 3])

abjad> cyclic_matrix[99][99]
3

Initialize from columns:

abjad> cyclic_matrix = sequencetools.CyclicMatrix(columns = [[0, 10, 20], [1, 11, 21], [2, 12, 22], [3, 13, 23]])

abjad> cyclic_matrix
CyclicMatrix(3x4)

abjad> cyclic_matrix[2]
CyclicTuple([20, 21, 22, 23])

abjad> cyclic_matrix[2][2]
22

abjad> cyclic_matrix[99]
CyclicTuple([0, 1, 2, 3])

abjad> cyclic_matrix[99][99]
3

CyclicMatrix implements only item retrieval in this revision.

Concatenation and division remain to be implemented.

Standard transforms of linear algebra remain to be implemented.

Read-only Properties

CyclicMatrix.columns

Read-only columns:

abjad> cyclic_matrix = sequencetools.CyclicMatrix([[0, 1, 2, 3], [10, 11, 12, 13], [20, 21, 22, 23]])

abjad> cyclic_matrix.columns
CyclicTuple([[0, 10, 20], [1, 11, 21], [2, 12, 22], [3, 13, 23]])

Return cyclic tuple.

CyclicMatrix.rows

Read-only rows:

abjad> cyclic_matrix = sequencetools.CyclicMatrix([[0, 1, 2, 3], [10, 11, 12, 13], [20, 21, 22, 23]])

abjad> cyclic_matrix.rows
CyclicTuple([[0, 1, 2, 3], [10, 11, 12, 13], [20, 21, 22, 23]])

Return cyclic tuple.
