(n_equations, n_sets, n_samples) or (n_sets, n_samples) of float.

valuesnumpy.ndarray

(n_parameters, n_samples) of float

errornumpy.ndarray, optional

(n_samples,) or () of float

masknumpy.ndarray, optional

(n_samples,) of bool

Returns:

alpha, betanumpy.ndarray, numpy.ndarray

A system of equations necessary to solve Ax=B where alpha (A) is of shape (coeffs, coeffs), beta (B) is of shape (coeffs,).
