treams.lattice.volume

treams.lattice.volume(a) = <ufunc 'volume'>

Calculate the signed volume (area)

From the vectors given in a, calculate the volume or area. This value is signed showing the handedness of the system. For a two-dimensional lattice calculates the area and the function has therefore as alias the name area.

Parameters:

a (float, (2,2)- or (3,3)-array) – Lattice vectors

Returns:

float
