So to summarize: given the SVD decomposition of x, x = u @ np.diag (s) @ vh the matrices returned by numpy.linalg.svd (x) are u, s and vh where vh is the hermitian conjugate of v. Other libraries and software will instead return v, causing the apparent inconsistency. It is a shame that different libraries ... WebIf sigma is None, eigsh requires an operator to compute the solution of the linear equation M @ x = b. This is done internally via a (sparse) LU decomposition for an explicit matrix M, or via an iterative solver for a general linear operator. Alternatively, the user can supply the matrix or operator Minv, which gives x = Minv @ b = M^-1 @ b. hauraki fm live https://annapolisartshop.com
