Removes nuclear spins from a spin system.

NewSys = nucspinrmv(Sys,rmvidx)

This function removes one or more nuclear spins from the spin system Sys and returns the resulting spin system in NewSys.

rmvidx specifies the indices of the nuclei to be removed. E.g., rmvidx=1 indicates the first nucleus, rmvidx=[2 4] indicates the second and the fourth nuclei.

First we define a spin system with 2 nuclei

Sys = struct('S',1/2,'g',[2 2 2.2]);
Sys = nucspinadd(Sys,'63Cu',[50 50 520]);
Sys = nucspinadd(Sys,'14N',[3 3 9],[],[-1 -1 2])

The following removes the nitrogen nucleus

Sys = nucspinrmv(Sys,2)
