The default behavior of MatrixForm is to treat the entire object, Level 0, as a Column, to treat Level 1 items as a Row, etc. You can either write the object as a true matrix or you can change the default behavior by using the TableDirections option.

I would think that the first "matrix" is 1x2 and the second is 2x1. Alternatively, how do I produce a 1x2 matrix? Many thanks in advance, Sam
