Editing a matrix' dimensions

[Tim Wessman]

Those really are for just when you are trying to insert a row or column inside an existing matrix/vector. The matrix/vector will automatically grow by one when you type in the empty boxes on an empty row/column.

To do a 3x4 for example, select and empty M1. Enter it, and you should see Go-> on the menu key. Type <number> ENTER <number> ENTER <number> ENTER. Now tap or arrow over to the col 2, row 2 position. Beging typing. The GO-> moves you to the right after each enter. When you hit the last col, you automatically move down to your next row.

This answer? Or are you seeing a different behavior?
