[Nfb-science] Matrix Computations in Linear Algebra

[Trevor Saunders]

Hi,

here's how you write a matrix in latex in math mode you use
\begin{bmatrix} matrix \end{bmatix} you'll need to be sing the amsmath
package.  Elements in a row are seperated by & and rows are seperated
by \\.

So two right a 2 by 2 matrix with top row left element 1 and right
element 2 and bottom row left 3 and right 4 you would have

\[
\begin{bmatrix}
1 & 2 \\
3 & 4 \\
\end{bmatrix}
\]
