I'd like my presentation to match the book's, and the book uses brackets around its matrices instead of parentheses. Is that doable? Is there a way, for example, to get `latex(A)` to generate
\left[\begin{array}{rrr} 6 & 6 & 1 \\ 7 & 0 & 6 \\ 4 & -7 & -7 \end{array}\right]
instead of
\left(\begin{array}{rrr} 6 & 6 & 1 \\ 7 & 0 & 6 \\ 4 & -7 & -7 \end{array}\right)
for some matrix A.mathochistTue, 09 Sep 2014 10:28:54 -0500http://ask.sagemath.org/question/24068/Plotting a latex matrix using text()http://ask.sagemath.org/question/9155/plotting-a-latex-matrix-using-text/I would like to plot a latex'd matrix at a location in a 2d plot. I tried this:
text('$\\left( \\begin{array}{ll} 2 & 3 \\\\ 4 & 5 \\end{array} \\right)$', (1,0) )
and various variations to do with the backslashes being escaped or not. But every time I get an error:
matplotlib.pyparsing.ParseFatalException: Expected end of math '$'
$\left( \begin{array}{ll} 2 & 3 \\ 4 & 5 \end{array} \right)$ (at char 0), (line:1, col:1)
It appears that matplotlib doesn't want to parse an array or a pmatrix etc. Is there a workaround?Kate StangeSat, 14 Jul 2012 02:04:17 -0500http://ask.sagemath.org/question/9155/
