Example
A=[1;2;3]; B=[2;3;4]; cross(A,B) //expected: [-1;2;-1] A=[%i,2,1+%i]; B=[1,%i,2+%i]; cross(A,B) //expected: [5+%i,2-%i,-3] A=[%t;%f;%t]; B=[%t;%f;%f]; cross(A,B) //expected: [0;1;0] |  |  |
vector cross product
C = cross(A,B)
real, complex, polynomial or boolean matrix of size 3-by-N or 1-by-3.
real, complex, polynomial or boolean matrix of same size as A.
real, complex, polynomial or boolean matrix of same size as A and B.
cross returns the cross product of A and B, that is:
C = A ∧ B
A and B can be full or sparse matrix. However, rational matrix are not supported.
Concerning boolean matrix, cross computes as if %t (resp. %f) was 1 (resp. 0), and '&' (resp. '|')
was '*' (resp. '+').
To finish, if A and B are 3-by-N matrix, column-wise computations are done.
A=[1;2;3]; B=[2;3;4]; cross(A,B) //expected: [-1;2;-1] A=[%i,2,1+%i]; B=[1,%i,2+%i]; cross(A,B) //expected: [5+%i,2-%i,-3] A=[%t;%f;%t]; B=[%t;%f;%f]; cross(A,B) //expected: [0;1;0] | | |
