scqubits.utils.spectrum_utils.get_matrixelement_table(operator, state_table)[source]#

Calculates a table of matrix elements.

Parameters:

  • operator (Union[ndarray, csc_matrix, dia_matrix, Qobj]) – operator with respect to which matrix elements are to be calculated

  • state_table (Union[ndarray, Qobj]) – list or array of numpy arrays representing the states |v0>, |v1>, … Note: state_table is expected to be in scipy’s eigsh transposed form.

Return type:

ndarray

Returns:

table of matrix elements
