I want to write block matrices like the one shown below
I tried underlining, fraction, and using __ as an entry by making three rows but they did not look nice.I want the horizontal lines inside the matrix to be gapped in between as shown. How can I do this?

This is one way:
Instead of dynamically varying brackets (
\left[
and\right]
), you may use fixed size brackets like\Bigg[
and\Bigg]
