Localized COSY pulse sequence. Syntax:
where H is the hamiltonian commutation superoperator, R is the relaxation superoperator and K is the chemical kinetics superoperator. The following parameters are required:
parameters.sweep sweep width, Hz
parameters.npoints number of points for both dimensions
parameters.spins nuclei on which the sequence runs, specified as '1H', '13C', etc.
parameters.delta the delay between the first two pulses of the sequence, seconds
