# rlx_split.m

Splits a relaxation superoperator into longitudinal, transverse and mixed components.

## Syntax

    [R1,R2,Rm]=rlx_split(spin_system,R)


## Description

The "mixed" components refer to all states that are not purely longitudinal or purely transverse, for example LxSz.

## Arguments

     R   - a relaxation superoperator in sphten-liouv
formalism


## Outputs

     R1  - the part of R acting on purely longitudinal
single-spin states

R2  - the part of R acting on purely transverse
single-spin states

Rm  - the rest of R
