We present an algorithm for efficiently computing the matrix approximation that requires the factorization of matrices of much smaller dimension than that of the original.
Web12 mrt. 2015 · 1 Answer Sorted by: 2 You can do this easily with Numpy broadcasting: a = np.array ( [0, 40, 80, 120]) b = np.array ( [0, 1, 2, 3]) c = a [:, None] + b [None, :] The statement a [:, None] is equivalent to a.reshape (1, -1), making a a column vector. Similarly, b [None, :] makes b a row vector. WebKronecker sums. A Kronecker sum between two square matrices of the same size is defined as. A \oplus B = A ⊗ I + I \oplus B\,. A⊕B = A⊗I + I ⊕B.
