Dear friends, I want to ask a question about the operation of Matrix: matr1={x1,y1,z1}; matr2={x2,y2,z3}; I want to get the result of this operation: OuterProduct=matr1 x matr2(this expression is the same as that in Linear Algebra .) The answer is:x3 = y1*z2 - y2*z1; y3 = z1*x2 - x1*z2; z3 = x1*y2 - x2*y1; OuterProduct = {x3, y3, z3}; How can I use any function included in Mathematica4 to calculate out the result ? I need the function to research the non-circular gears geometry .If anyone is good at the area, please send message to me .
