I'm writing a paper in IEEE journal format. I have a BIG matrix as follows:
\begin{align}
\begin{bmatrix}
\begin{pmatrix}
E^\top KA &0 \\
0 &V^\top E^\top U \hat{K} U^\top AV
\end{pmatrix} +
\begin{pmatrix}
A^\top KE &0 \\
0 &V^\top A^\top U \hat{K} U^\top EV
\end{pmatrix}
&\begin{pmatrix}
E^\top KB \\
V^\top E^\top U \hat{K} U^\top B
\end{pmatrix} \\
\begin{pmatrix}
B^\top KE &B^\top U \hat{K}U^\top EV
\end{pmatrix}
&0
\end{bmatrix} + \cr
\begin{bmatrix}
\begin{pmatrix}
C^\top C &-C^\top CV \\
-V^\top C^\top C &V^\top C^\top CV
\end{pmatrix}
&0 \\
0 &-\gamma^2 I
\end{bmatrix} = Q_2 \preceq 0
\end{align}
How can i make it fit in the two column paper format? I am relatively new to LaTeX. Thanks in advance.
