"I must not fear. Fear is the mind killer. Fear is the little death that brings total obliteration. I will face my fear. I will permit it to pass over me and through me. And when it has gone I will turn the inner eye to see its path. Where the fear has gone there will be nothing. Only I will remain." - The Litany Against Fear, "Dune" by Frank Herbert

If you use pmatrix, you don't have to insert the parentheses "by hand".

[math]\begin{pmatrix} a & b & c \\ d & e & f \\ g & h & i \end{pmatrix}[/math] gives .

For a bracketed matrix, use bmatrix. For a determinant, use vmatrix.

[math]\begin{bmatrix} a & b & c \\ d & e & f \\ g & h & i \end{bmatrix}[/math] gives .

[math]\begin{vmatrix} a & b & c \\ d & e & f \\ g & h & i \end{vmatrix}[/math] gives .
