scipy.linalg.orth(A, rcond=None)[source]

Construct an orthonormal basis for the range of A using SVD

Parameters:

A : (M, N) array_like

Input array

rcond : float, optional

Relative condition number. Singular values s smaller than rcond * max(s) are considered zero. Default: floating point eps * max(M,N).

Returns:

Q : (M, K) ndarray

Orthonormal basis for the range of A. K = effective rank of A, as determined by rcond
