When a is a 2D array, and full_matrices=False, then it is factorized as u @ np.diag (s) @ vh = (u * s) @ vh, where … 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.
