Next, we’re going to put a little extra space between the vertical bars and the

elements of the matrix. This is purely a matter of taste, so you can skip this part if

you’d prefer to keep your matrix looking the way it does at present. Before we

enter the spaces, we need to position the insertion point so that it’s inside the

vertical bars but to the left of and outside the matrix. You can do this by clicking

somewhere near the position indicated by the arrow pointer in the preceding

picture. Then just enter one or two thin spaces by pressing C

TRL+SPACEBAR. Do

the same on the right-hand side of the matrix. If you choose the Show All

command from the View menu, you’ll be able to see your spaces. They should

look like this:

7. After the brief digression in Step 6, it’s now time to correct the entries in our

matrix. First, delete the

λ from the upper right slot. The quickest way to do this is

to place the insertion point to the right of it and press B

ACKSPACE (or Backspace).

Do the same with the

λ in the lower left slot. Notice that MathType adjusts the

spacing after the minus signs to reflect the fact that they are now unary operators

rather than binary operators (negation rather than subtraction).

8. Change all the subscripts in the matrix to their desired values. The “11” in

the upper left slot is correct already, but we should have “12” in the upper right

slot, “21” in the lower left, and “22” in the lower right. You can double-click on

the existing subscripts to select them, and then type the correct values over them,

just as you would in a word processor. Your equation should now look like this:

Modifying a Matrix

The Matrix submenu on

the Format menu

contains commands for

adding and deleting

rows and columns.

9. The equation is now essentially complete, although there are a few more

formatting options that you may want to try out. First, you might want to shift

the entire matrix down so that its top row is aligned with the rest of the equation.

To do this, place the insertion point anywhere in the matrix and choose Align at

Top from the Format menu. Also, it might be nice to right justify the entries in

each column. To do this, place the insertion point somewhere in the matrix,

choose the Change Matrix command from the Matrix submenu on the Format

menu, and click on the button labeled “Right” in the dialog box.

Finally, if you object to the fact that MathType tightened the spacing after the

unary minus signs, you can put the spaces back in again, though this would

mean deviating from standard typesetting conventions. They should be thick

spaces (one third of an em). The thick space is the middle one in the second row
