I have a large matrix
\begin{align}
\begin{bmatrix}
\bigg(m\Gamma_1(\kappa_1^1)\omega_1\mathbf{h}_0\mathbf{P}_1^\varepsilon + m\Gamma_2(\kappa_1^1)\sin\bigg(\frac{2\omega_1\bar\zeta x_3}{\varepsilon}\bigg)\omega_1\mathbf{h}_1\mathbf{P}^\varepsilon_1 \\
+ m\Gamma_2(\kappa_1^1)\cos\bigg(\frac{2\omega_1\bar\zeta x_3}{\varepsilon}\bigg)\omega_1\mathbf{h}_2\mathbf{P}_1^\varepsilon\bigg) & \mathbf{0} & \dots & \mathbf{0} \\
\mathbf{0} & \ddots & \ddots & \vdots \\
\vdots & \ddots & \ddots & \mathbf{0} \\
\mathbf{0} & \dots & \mathbf{0} & X
\end{bmatrix}
\end{align}
where I want to insert
\begin{align}
&\bigg(m\Gamma_1(\kappa_1^M)\omega_M\mathbf{h}_0\mathbf{P}_1^\varepsilon + m\Gamma_2(\kappa_1^M)\sin\bigg(\frac{2\omega_M\bar\zeta x_3}{\varepsilon}\bigg)\omega_M\mathbf{h}_1\mathbf{P}^\varepsilon_M \\
&+ m\Gamma_2(\kappa_1^1)\cos\bigg(\frac{2\omega_M\bar\zeta x_3}{\varepsilon}\bigg)\omega_M\mathbf{h}_2\mathbf{P}_M^\varepsilon\bigg)
\end{align}
where the "X" is located. What is the best procedure on how to achieve this>?>?

I would place both the top-left and bottom-right elements of the
bmatrix
environment on separate lines.I would also use inline-fraction notation for the trigonometric terms, saving a lot of vertical space.
Addendum: The OP has indicated in a comment that the big matrix is block-diagonal. Incorporating this information, one may re-state the material much more succinctly as
