# Some matrix help

I have been trying for a while with the use of previous questions without luck.

Making the matrix itself is no problem,

\begin{equation*}
\begin{pmatrix}
k_0 \times k \\
k_1 \times k \\
k_2 \times k \\
\vdots \\
k_N \times k \\
\end{pmatrix}.
\end{equation*}


But I want to have a curly bracket on the left side of the matrix indicating that the sum of k's = k like this:

k{


Thanks

• I am not sure I understand the question but perhaps k\left\{\begin{pmatrix...\end{pmatrix}\right. ? – David Carlisle May 5 at 10:49
• Well that was simple, thanks a lot! – emilk May 5 at 13:36

$k\left\{\begin{pmatrix} ...\end{pmatrix}\right.$
