WebOne way we can initialize NumPy arrays is from Python lists, using nested lists for two- or higher-dimensional data. For example: >>> a = np.array( [1, 2, 3, 4, 5, 6]) or: >>> a = np.array( [ [1, 2, 3, 4], [5, 6, 7, 8], [9, 10, 11, 12]]) We can access the elements in the array using square brackets.

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, … WebNote: numpy.linalg.eigh will consider only the upper triangular part or lower triangular part of the matrix to calculate eigenvalues (one part is like the mirror image of the other for these special matrices). So if you pass a matrix which is neither symmetric nor Hermitian to get orthogonal eigenvectors, it will construct a symmetric matrix ...
