SquareComplexMatrix

class SquareComplexMatrix(*args)

Complex square matrix.

Parameters
sizeint, n > 0, optional

Matrix size. Default is 1.

valuessequence of complex with size n^2, optional

Values. OpenTURNS uses column-major ordering (like Fortran) for reshaping the flat list of values. Default creates a zero matrix.

Examples

Create a matrix

>>> import openturns as ot
>>> M = ot.SquareComplexMatrix(2, range(2 * 2))
>>> print(M)
[[ (0,0) (2,0) ]
 [ (1,0) (3,0) ]]

Get or set terms

>>> print(M[0, 0])
0j
>>> M[0, 0] = 1.0
>>> print(M[0, 0])
(1+0j)
>>> print(M[:, 0])
[[ (1,0) ]
 [ (1,0) ]]

Create an openturns matrix from a square numpy 2d-array (or matrix, or 2d-list)…

>>> import numpy as np
>>> np_2d_array = np.array([[1.0, 2.0], [3.0, 4.0]])
>>> ot_matrix = ot.SquareComplexMatrix(np_2d_array)

and back

>>> np_matrix = np.matrix(ot_matrix)
