I can't seem to be able to figure out how to insert a block matrix into LyX. I see how to add a vertical bar between columns, but not a horizontal bar between rows. Any suggestions?
A matrix with horizontal lines is in LaTeX's definition a table. How to handle tables and their lines is described in detail in sec. 2 of the EmbeddedObjects manual that you find in LyX's Help menu.
