Concerning vectors, there should be a cross-product function, the dot-product is there.
The discussion about Rect/Polar conversion showed us how we can do that (for 3-dim vectors):
X001 LBL X
X002 ABS
X003 CLx
X004 LASTx
X005 RDN
X006 RDN
X007 [
[0,[0,0,-1]*REGT,[0,1,0]*REGT]*REGZ,
[[0,0,1]*REGT,0,[-1,0,0]*REGT]*REGZ,
[[0,-1,0]*REGT,[1,0,0]*REGT,0]*REGZ
]
X008 REGZ
X009 RDN
X010 RTN
Lines 2-4 and 8-9 could be omitted. They copy T to Z and X to LASTx.
Line 7 is a nightmare to edit I now. But don't blame me for that. I hope it's easier to read spread over five lines.
RDN means Roll down.
