Vector Cross Product
Vector or cross product
cross(x, y)
x |
numeric vector or matrix |
y |
numeric vector or matrix |
Computes the cross (or: vector) product of vectors in 3 dimensions. In case of matrices it takes the first dimension of length 3 and computes the cross product between corresponding columns or rows.
The more general cross product of n-1 vectors in n-dimensional
space is realized as crossn.
3-dim. vector if x and < are vectors, a matrix of
3-dim. vectors if x and y are matrices themselves.
cross(c(1, 2, 3), c(4, 5, 6)) # -3 6 -3
