Double left brace including several lines in eqnarray with an arrow between
2,136
Probably you want this? It uses the extensible arrows from amsmath
and the dcases
(=display style cases) environment from mathtools
(a particularly useful extension of amsmath
).
\documentclass[11pt]{article}
\usepackage{mathtools}
\begin{document}
\begin{equation}
\begin{dcases}
\textsf{blabla 1} \\
\textsf{blabla 2} \\
\textsf{blabla 3} \end{dcases}
\xRightarrow{~\textsf{blabla4}~}
\begin{dcases}
\textsf{blabla 5} \\
\textsf{blabla 6} \\
\textsf{blabla 7}
\end{dcases}
\end{equation}\
\end{document}

I m trying to write two systems of equations with "left brace" separated with a long arrow as on the figure below.
I try with this kind of code but it doesnt work...The two systems are not aligned. One is at the bottom
\begin{equation} \left\{ \begin{array}{ll} blabla1 \\ \vspace{0.01cm} \\ blabla2 \\ \vspace{0.01cm} \\ blabla 3 \\ \end{array} \right. \Longrightarrow \left\{ \begin{array}{ll} blabla5 \\ \vspace{0.01cm} \\ blabla6 \\ \vspace{0.01cm} \\ blabla7 \\ \end{array} \right. \end{equation}\

LaRiFaRi almost 6 yearsWelcome to TeX.SX! What do you mean by "it doen't work"? Errors, warnings, no output? We will have to see a compilable example of this. Appart of the very last slash and all those empty lines, your code runs fine for me.

campa almost 6 yearsDo not leave blank lines in math environments: this will produce a bunch of errors and quite likely the "One is at the bottom" bit.

ThomasGuenet almost 6 yearsWorks perfectly to me.
