TriangularComplexMatrix

class TriangularComplexMatrix(*args)

Hermitian Matrix.

Parameters:
dimint

The dimension of the triangular matrix (square matrix with dim rows and dim columns).

isLowerbool, optional

Flag telling if the matrix is triangular lower (True) or upper (False). Default is True.

Notes

The triangular complex matrix is filled with (0, 0). It is not possible to fill the matrix from a collection of complex values (to be done later).
