qics.vectorize.lin_to_mat

qics.vectorize.lin_to_mat(lin, dims, iscomplex=False, compact=(False, True))

Computes the matrix corresponding to a linear map from vectorized symmetric matrices to vectorized symmetric matrices.

Parameters:

lincallable

Linear operator sending symmetric matrices to symmetric matrices.

dimstuple of int

The dimensions (ni, no) of the input and output matrices of the linear operator.

iscomplexbool, optional

Whether the matrix to vectorize is Hermitian (True) or symmetric (False). Default is False.

compacttuple of bool, optional

Whether to use a compact vector representation or not for the input and output matrices, respectively. Default is (False, True).

Returns:

ndarray

The matrix representation of the given linear operator.
