LaTeX matrix when publishing

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.

If you want to experiment then see http://uk.mathworks.com/matlabcentral/answers/232055-is-there-a-hook-that-will-allow-me-to-change-the-document-style-and-or-add-packages-to-the-latex-fil#answer_187995

I don't care necessarily if it's a bmatrix, just any way I can get a matrix to show up in latex?

[Walter Roberson]

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].
