tbplas.frac2cart

tbplas.frac2cart(lat_vec: ndarray, frac_coord: ndarray, origin: ndarray = array([0., 0., 0.])) → ndarray

Convert fractional coordinates to Cartesian coordinates. :param lat_vec: (3, 3) float64 array

Cartesian coordinates of lattice vectors, with each ROW being a vector

Parameters:

• frac_coord – (num_coord, 3) float64 array fractional coordinates to convert in basis of lattice vectors

• origin – (3, ) float64 array Cartesian coordinate of lattice origin

Returns:

(num_coord, 3) float64 array Cartesian coordinates converted from fractional coordinates
