\begin{document}
To show the effect of the matrix on surrounding
lines inside a paragraph, we put it here:
  $ \left( \begin{smallmatrix}
              1 & 0 \\ 0 & -1
           \end{smallmatrix}  \right) $
and follow it with enough text to ensure that
there is at least one full line below the matrix.
