into:

Try the transpose operator: given a matrix X, then the transpose is X.'

If the 3x3 blocks are symmetric, as in your example, a simple transpose is all you need. If, more generally, they are not, however,I would recommend MAT2TILES ( Download ) as follows
C=mat2tiles(YourMatrix,[3,3]);
YourMatrixReshaped = cell2mat(C.')

Mathematically correct, but it probably would be still best to introduce beginners to the nonconjugate transpose: .'

If your original matrix is A, then transpose it:
B = A'
[This is actually the complex conjugate transpose, but assuming your matrix is real, that's OK. You can read more with "doc transpose" and "doc ctranspose".]
