        method to calculated the interpolation of lattice parameters and unit
        cell angles of the Alloy. By default linear interpolation between the
        value of material A and B is performed.

        Parameters
        ----------
        latA, latB :    float or vector
            property (lattice parameter/angle) of material A and B.  A property
            can be a scalar or vector.
        x :             float
            fraction of material B in the alloy.
        name :          str, optional
            label of the property which is interpolated. Can be 'a', 'b', 'c',
            'alpha', 'beta', or 'gamma'.
