mufloat, optional

Friction coefficient value.

penaltybool, optional

if True then return penalty matrix.

friction_netbool, optional

Friction net formulation if True for the penalty formulation, friction plus formulation if True.

Returns:

csr_matrix

Afr (penalty=False) or Afr@B (penalty=True)
