|
||||
- You can use \c \\left. or \c \\right. to have only right or only left brace
|
||||
.
|
||||
|
||||
In additional fixed-size parantheses are available with the following family of instructions:
|
||||
- \c \\bigl([\\{\\langle... , \c \\big([\\{\\langle... and \c \\bigr)]\\}\\rangle... \image html jkqtmathtext/jkqtmathtext_brace_big.png
|
||||

- \c \\Biggl([\\{\\langle... , \c \\Bigg([\\{\\langle... and \c \\Biggr)]\\}\\rangle... \image html jkqtmathtext/jkqtmathtext_brace_bbigg.png
|
||||
.
|
||||
They use the same rendering code as the standard \c \\left and \c \\right instructions. Here is an example:
|
||||
\image html jkqtmathtext/jkqtmathtext_brace_bigfamily.png generated by <code> $\Biggl\langle\biggl\{\Bigl[\bigl( r^{123}\bigr)\Bigr]\biggr\}\Biggr\rangle$</code>
