Obliterates all interactions and populations in the subspace of states that involve user-specified spins in any way. The specified spins would not contribute to the system dynamics until the Liouvillian is rebuilt from scratch. Syntax:
spins: spins to be wiped, specified either by name, such as '13C', or by a list of numbers, such as [1 2 3].
L: Liouvillian superoperator
rho: state vector or a horizontal stack thereof
Note: this function is an analytical equivalent of a running decoupling pulse sequence on the specified spins.
Note: this function requires sphten-liouv formalism.
