Why won't MATLAB accept my bmatrix syntax?

[gfd43tg]

Hello,

I am trying to publish a file on matlab, and for some reason it won't accept my code, even though it works on this forum. Does MATLAB use some other syntax for matrices?

$$ \vec {x} = \begin {bmatrix} T-T_{s} \\ C_{A} - C_{As} \\ C_{P} - C_{Ps} \end {bmatrix}$$

I've never mixed Matlab with LaTeX, but bmatrix is not part of LaTeX, it is an AMS extension.

You have to do matrices in regular LaTeX "manually," something like

\left[ \begin{array}{c} a \\ b \\ c \end{array} \right]

Thank you, that fixed it.

I still don't understand why MATLAB won't accept this, but the latex on PF will (what is going on with the dCA/dt term !?)

$$ \vec {\dot {x}} = \left[ \begin{array}{c} \frac {dT}{dt} \\ \frac
% {dC_{A}}{dt} \\ \frac {dC_{P}}{dt} \end{array} \right] = \left[ \begin{array}{c} -\frac{F}{V} & F \frac {\Delta H_{rxn}}{\rho V c_{p}} & \frac {\beta}{\rho V c_{p}} \frac {1}{2 \sqrt{C_{P}}} \\ 0 & -\frac {F}{V}-2kC_{A} & 0 \\ 0 & 2kC_{A} & - \frac {F}{V} \end{array} \right] $$

According to the doc, http://www.mathworks.com/help/matla...matlab-comments-for-publishing.html#btj5jsh-1

"MATLAB publishing supports standard LaTeX math mode directives. Text mode directives or directives that require additional packages are not supported."

So any markup that requires a package (such as amsmath) is out.

EDIT: It appears that you can add packages by modifying a source file. See this thread for more info:
