cross(
VECTR MATH menu
cross( vectorA , vectorB )
Returns the cross product of two real or complex
vectors, where:
cross([a,b,c],[d,e,f]) = [bf N ce cd N af ae N bd]
Both vectors must have the same dimension (either 2 or
3 elements). A 2-D vector is treated as a 3-D vector with
0 as the third element.
cross([1,2,3],[4,5,6]) b
[ L 3 6 L 3]
cross([1,2],[3,4]) b
