Python bc_block_plus_ident Beispiele

Beispiel #1

def test_block_plus_ident():
    A = MatrixSymbol('A', n, n)
    B = MatrixSymbol('B', n, m)
    C = MatrixSymbol('C', m, n)
    D = MatrixSymbol('D', m, m)
    E = MatrixSymbol('E', n, n)
    X = BlockMatrix([[A, B], [C, D]])
    assert bc_block_plus_ident(X+Identity(m+n)) == \
        BlockDiagMatrix(Identity(n), Identity(m)) + X
    assert bc_block_plus_ident(A + Identity(n)) == A + Identity(n)
    assert bc_block_plus_ident(A + E) == A + E
