Brackets with matrices look ugly!
For background, we start with an overview of the matrix command.
Markup Result
matrix { a # b ## c # d }
a b
c d
Note
Rows are separated by two #’s and entries within each row are separated
by one #.
The first problem people have with matrices is that brackets do not scale with the
matrix.
Markup Result
( matrix { a # b ## c # d } )


c d

Math provides scalable brackets. That is, the brackets grow in size to match the size
of their contents. Use the commands left( and right) to make scalable brackets.
Markup Result
left( matrix { a # b ## c # d } right)

a b
c d

Tip
Use left[ and right] to obtain square brackets.
