Compute <z,w>_L = -z0 w0 + z1 w1 + z2 w2 row-wise for points in the
Lorentz model. Vectors and matrices with three columns are accepted.
Arguments
- z
A numeric vector of length 3 or an n x 3 matrix.
- w
A numeric vector of length 3 or an n x 3 matrix.
Value
A numeric vector of Lorentz inner products.
Examples
z <- c(cosh(1), sinh(1), 0)
lorentz_inner(z, z)
