Re: [問題] questions about vertical line in the …
※ 引述《carex ()》之銘言：
: I am having trouble doing something like thes
: \begin{eqnarray}
: \left.{[\hat{\mathbf{H}}]_{i,j}=\frac{\partial^2
: v_B(\mathbf{\Theta})}{\partial \theta_i \partial
: \theta_j}}\right|_{\mathbf{\Theta}=\hat{\mathbf{\Theta}}_B}
: \end{eqnarray}
: but the | is not long enough. Is there anyone who knows how to draw
: this kind of vertical line? All suggestions are highly appreciated.
我沒辦法用推文表達 ^^
