radtools.Cell.params

radtools.Cell.params(cell)

Return lattice parameters from cell.

Added in version 0.7.

Parameters:

cell(3,3) array-like

Cell matrix, rows are interpreted as vectors.

cell = [[a1_x, a1_y, a1_z],
        [a2_x, a2_y, a2_z],
        [a3_x, a3_y, a3_z]]

Returns:

afloat

Length of the \(a_1\) vector.

bfloat

Length of the \(a_2\) vector.

cfloat

Length of the \(a_3\) vector.

alphafloat

Angle between vectors \(a_2\) and \(a_3\). In degrees.

betafloat

Angle between vectors \(a_1\) and \(a_3\). In degrees.

gammafloat

Angle between vectors \(a_1\) and \(a_2\). In degrees.
