Matrix environments

The matrix environments are array, matrix, pmatrix, bmatrix, Bmatrix, vmatrix, Vmatrix, and smallmatrix. Each provides a table for expressions, aligned in rows and columns. The main difference between the various types of matrix is the kind of delimeters that surround them.

Each row of a matrix ends with two backslashes (\\). Each column ends with an ampersand (&).
