LaTeX matrix when publishing
显示 更早的评论
Hello,
I'm trying to publish some latex, and for some reason it is not accepting my matrix. I have tested on another site and it seems to work, but I am wondering if the syntax for matlab latex is different from other places
% $$ \vec {x} = \begin {bmatrix} T-T_{s} \\ C_{A} - C_{As} \\ C_{P} - C_{Ps} \end
% {bmatrix} $$
Is not making a matrix for me. What is wrong?
This is the output on the published file
Error updating Text.
String must have valid interpreter syntax:
$$ \vec {x} = \begin {bmatrix} T-T_{s} \\ C_{A} - C_{As} \\ C_{P} - C_{Ps} \end {bmatrix}

bmatrix is part of amsmath but you cannot (at all easily) load the ams* packages.

Yes, see for example
str = '$\begin{array}{ccc}a & b & c \\ d & e & f \\g & h & i \end{array}$';
text(0.5,0.5,str, 'Interpreter', 'latex')
For the purpose of publish try
% $\begin{array}{ccc}a & b & c \\ d & e & f \\g & h & i \end{array}$
It might matter that everything is on one line: I do not know enough about publish for that. Also perhaps you need $$ for publish instead of just $ -- I have not used publish myself.

Just had the very same issue! Strangely enough the
pmatrix
Call works just fine. If I use the following:
%%
%
% $$\hat{\mathbf{x}}_k = \pmatrix{x \cr
% y \cr
% \dot{x} \cr
% \dot{y} \cr}$$
then I get a nicely formatted vector, but with parentheses. If I use
'bmatrix'
I get the same error you report. In the end I decided that I'd just have to live with parentheses rather than try and use some extreme TeX-Fu. Hope this helps.

pmatrix is part of the mathtools package, but bmatrix is part of the amsmath package.

If you want square braces use \matrix{} enclosed with \left[ \right].
