Calculate cross product of two 3-by-1 vectors

Description

The 3x3 Cross Product block computes cross (or vector) product of two vectors, A and B, by generating a third vector, C, in a direction normal to the plane containing A and B, and with magnitude equal to the product of the lengths of A and B multiplied by the sine of the angle between them. The direction of C is that in which a right-handed screw would move in turning from A to B.

A=a1i+a2j+a3kB=b1i+b2j+b3kC=A×B=|ijka1a2a3b1b2b3|=(a2b3a3b2)i+(a3b1a1b3)j+(a1b2a2b1)k
