pytc.legacy.df.test_multi_accuracy(rho1, rho2, n_rank1, n_rank2)

Test reconstruction accuracy for two densities using fused pivots.

Parameters:

• rho1 (numpy.ndarray) – Input densities to approximate

• rho2 (numpy.ndarray) – Input densities to approximate

• n_rank1 (int) – Desired ranks for each density

• n_rank2 (int) – Desired ranks for each density

Returns:

Relative error for rho1 reconstruction abs_error1: Absolute error for rho1 reconstruction rel_error2: Relative error for rho2 reconstruction abs_error2: Absolute error for rho2 reconstruction n_fused: Number of fused pivots used

Return type:

rel_error1
