For the following matrices, first find a basis for the column
space of the matrix. Then use the Gram-Schmidt process to find an
orthogonal basis for the column space. Finally, scale the vectors
of the orthogonal basis to find an orthonormal basis for the column
space.
(a) [1 1 1, 1 0 2, 3 1 0, 0 0 4 ] b) [?1 6 6, 3 ?8 3, 1 ?2 6, 1
?4 ?3 ]
