Homospoil.m

Emulates a strong homospoil pulse - only zero-frequency states with respect to the carrier frequencies (chemical shifts are not considered) survive the process.

Syntax

    rho=homospoil(spin_system,rho,zqc_flag)

Arguments

        rho - a state vector or a horizontal stack thereof

   zqc_flag - a flag controlling the fate of zero-quantum 
              coherences. If set to 'keep', causes ZQCs to
              survive the process, approximating experimen-
              tal behaviour. If set to 'destroy', wipes the
              zero-quantum coherences - only the longitudi-
              nal states survive the process.

Outputs

       rho  - the state vector(s) with only the longitudi-
              nal or only the zero-quantum states kept

Notes

This function is only available for sphten-liouv formalism; it supports Fokker-Planck direct products.
