In my example below, I need to write it "nicely", i.e., to have the array with ones smaller, less space around,...Anyone knows how to do it?





\vX_1 = -\rho\vP^{o}\vT-\rho\vP^g\big(\left(
\right)\otimes \vI\big)\vN,

  • 2
    \left(\begin{smallmatrix}1\\1\end{smallmatrix}\right) – egreg Mar 6 '15 at 22:11

You may want to use the smallmatrix environment, which is provided by the amsmath package, encased in big-sized parentheses:

enter image description here



\vX_1 = -\rho\vP^{o}\vT-\rho\vP^g\bigl(
        \bigl(\begin{smallmatrix} 1\\1 \end{smallmatrix} \bigr)
        \otimes \vI\bigr)\vN

Addendum: If one leaves off the \big modifiers around the smallmatrix, one gets

You may, or may not, prefer this look to the one shown above.

  • Almost the same as mine, but: 1. the \newcommand lines should be before \begin{document} and 2. \nonumber should not be used, preferring equation*. – egreg Mar 6 '15 at 22:16
  • @egreg - good points, I'll make the changes. – Mico Mar 6 '15 at 22:17
  • Oh, and if you use \left( and \right) around the smallmatrix, the result will be even better (you can see it in my deleted answer). – egreg Mar 6 '15 at 22:18
  • @egreg - Thanks, implemented your follow-up suggestion as well. :-) – Mico Mar 6 '15 at 22:27
