* VCROSS vd, vs1, vs1
Result is the cross product of x and y, i.e., the resulting components are, in order:
## Vector dot product
+* SUBVL=1, rd SUBVL=2,3,4 vs1,vs2
+* rd=scalar, SUBVL=default, vs1, vs2=vec
+
* VDOT rd, vs1, vs2
Computes the dot product of two vectors. Internal accuracy must be
## Vector length
