About B0 field design

[Stravvberry1]

Dear MRILAB members,

I want to do some research on artifact caused by inhomogeneous field, first I want to check the code describing magnetic field interpolation and signal integration within a single voxel to see if I need to do some change. My programming is poor，so could you please tell me the specific location of this code?(in which folder and the specific name).

I would appreciate it if you could reply to me.
