When you select a matrix, the Matrix Editor opens. The menu items in the Matrix Editor are:
• : copies the selected element to the entry line where it can be edited. This item is only
visible when an element in the matrix or vector is selected.
• : displays a menu for you to choose to insert a row above the current row or a column
to the left of the current column
• : displays a menu for you to choose the small font, medium font, or large font
• or : sets the direction the cursor moves after an element has been entered
• : displays a menu for you to choose how many columns to display at one time: one, two, three, or four
You don’t have to define the dimensions of a matrix beforehand. Just start entering elements. You
can enter values row by row, or column by column.
In programs and in Home view, you can refer to a matrix or vector by its name (M1, M2, etc.). For
example, suppose M6 is composed of [[8,0,5],[5,1,6]] and M7 is composed of [[1,2,3],[4,5,6]]. In
Home view, you could enter M6+M7. The result displayed is [[9,2,8],[9,6,12]].
You can create a matrix or vector in Home view by pressing S 5 and entering each element. Use
the cursor keys to move from slot to slot in the matrix template that appears.
Numerous matrix-related functions are available on the Math menu (see page 53).
