adcc.guesses_spin_flip(matrix, n_guesses, block='ph', **kwargs)

Obtain guesses for computing spin-flip states by inspecting the passed ADC matrix.

matrix The matrix for which guesses are to be constructed n_guesses The number of guesses to be searched for. Less number of

vectors are returned if this many could not be found.

block Diagonal block to use for obtaining the guesses

(typically “ph” or “pphh”).

kwargs Any other argument understood by guesses_from_diagonal.
