extprod3d: Compute external- or 'cross'- product of 3D vectors.
In geometry: Mesh Generation and Surface Tessellation
extprod3d R Documentation
Compute external- or ‘cross’- product of 3D vectors.
Description
Computes the external product
\left(x_2 y_3 - x_3 y_2,\;
x_3 y_1 - x_1 y_3,\;
x_1 y_2 - x_2 y_1 \right)
of the 3D vectors in x and y.
Usage
extprod3d(x, y, drop = TRUE)
Arguments
x
n-by-3 matrix. Each row is one x-vector
y
n-by-3 matrix. Each row is one y-vector
drop
logical. If TRUE and if the inputs are one row
matrices or vectors, then delete the dimensions of the array
returned.
Value
If n is greater than 1 or drop is
FALSE, n-by-3 matrix; if n is 1 and
drop is TRUE, a vector of length 3.
