Hi all,
I have two vector field J1 and J2, in 3D space (x,y,z) and calculated at some discrete points (extracted in a txt file from comsol.
I need to volume integrate the triple_integration of (J1 dot J2), which is expressed as
triple_integration ( J1(x)*J2(x) + J1(y)*J2(y) + J1(z)*J2(z) ).
I have found that http://wwwusers.math.umd.edu/~jmr/241/tripleint.html , but in my case, I have no analytically expression of the funstion. I guess I could interpolate using TriScatinterp, but is any other way to do that?
