athena.active.ActiveSubspaces._rotate_x

ActiveSubspaces._rotate_x(reduced_inputs, inactive_inputs)

A convenience function for rotating subspace coordinates to x space.

Parameters

• reduced_input (numpy.ndarray) – the value of the active variables.

• inactive_inputs (numpy.ndarray) – the value of the inactive variables.

Returns

(n_samples * n_points)-by-n_params matrix that contains points in the original parameter space, (n_samples * n_points)-by-n_params matrix that contains integer indices. These indices identify which rows of the previous matrix (the full parameters) map to which rows of the active variables matrix.

Return type

numpy.ndarray, numpy.ndarray
