cross

Cross product of two 3-element vectors.

Syntax

C = cross(A, B)
C = cross(A, B, dim)

Description

Returns the 3-element cross product A × B. A and B must each have a length-3 dimension; for matrices, cross operates along the first dimension of size 3 by default, or along dim if specified.

Examples

cross([1 0 0], [0 1 0])     % [0 0 1]   (i × j = k)
A = [1 2; 3 4; 5 6];        % 3×2
B = [7 8; 9 10; 11 12];
cross(A, B)                 % 3×2 with column-wise cross products
