Error in matrix decomposition in sacs
WebCompute Schur decomposition of a matrix. The Schur decomposition is: A = Z T Z^H. where Z is unitary and T is either upper-triangular, or for real Schur decomposition (output=’real’), quasi-upper triangular. In the quasi-triangular form, 2x2 blocks describing complex-valued eigenvalue pairs may extrude from the diagonal. Parameters: WebI saw this formula in a textbook: squared Frobenius norm of the original matrix $\\mathbf X$ minus its truncated SVD $\\mathbf X_k$ (which can be seen as the approximation error) equals the sum of sq...
