Appendix D: kernel data structures

There are two major data structures that are used throughout Spinach: spin_system, which contains spin system topology, interaction and basis set information, and parameters, which contains pulse sequence parameters. The spin_system structure is generated by the create.m function and updated by the basis.m function during the initialization stage.
