How to make an equation span the whole page / line in LaTeX?
- by Reed Richards
I have this equation and it's quite big (basically a FDM one) but it aligns with the text and then continues out on the right side to the nothingness. I've tried stuff like \begin{center} and \hspace*{-2.5cm} but to no avail. I want it to use the whole line not just from the left-margin and out to the right.
How do I do it and do I need to install some special package for it?
I use the \[ instead of the displaymath like this

The code
\[
\left(
\begin{array}{cccccc}
-(2\kappa+\frac{hV\rho}{2}) & (\frac{hV\rho}{2}-\kappa) & 0 & \cdots & 0 \\
-\kappa & -(2\kappa+\frac{hV\rho}{2}) & (\frac{hV\rho}{2}-\kappa) & 0 & \cdots \\
0 & -\kappa & -(2\kappa+\frac{hV\rho}{2}) & (\frac{hV\rho}{2}-\kappa) & 0 & \cdots \\
\vdots & 0 & \ddots & \vdots \\
\vdots & \vdots & \vdots & -\kappa & -(2\kappa+\frac{hV\rho}{2}) & (\frac{hV\rho}{2}-\kappa) \\
0 & \vdots & \vdots & 0 & \kappa - \frac{2h\kappa_{v}}{\kappa}(\frac{hv\rho}{2} - \kappa) & -2\kappa \\
\end{array}
\right)
\left(
\begin{array}{c}
T_{1} \\
T_{2} \\
\vdots \\
T_{n} \\
\end{array}
\right)
=
\left(
\begin{array}{c}
Q(0) + \kappa T_{0} \\
Q(h) \\
Q(2h) \\
\vdots \\
Q((n-1)h) \\
2\frac{\kappa_{v}}{\kappa_{v}}T_{out} \\
\end{array}
\right)
\]
