Dqf cosy.m

Phase-sensitive double-quantum filtered COSY pulse sequence.

Syntax

    fid=dqf_cosy(spin_system,parameters,H,R,K)

Arguments

   parameters.sweep        sweep width in Hz

   parameters.npoints      number of points for both dimensions

   parameters.spins        nuclei on which the sequence runs,
                           specified as '1H', '13C', etc.

   H  - Hamiltonian matrix, received from context function

   R  - relaxation superoperator, received from context function

   K  - kinetics superoperator, received from context function

Outputs

   fid.cos, fid.sin  -  components of the free induction
                        decay for hypercomplex processing

Examples
