[O] how to pass parameters to latex environment when exporting

[Uwe Brauer]

Hi 

I have the following example of a org file 

#+begin_solution
The result is as follows
#+begin_src matlab :results output raw :exports results  :eval never-export 
l=0.33;
mypois=poisspdf(0,l);
myres=1-poisspdf(0,l)-poisspdf(1,l);
disp('\begin{align*}')
fprintf('P(X\\geq 1)&=1-P(X=0)-P(X=1)=1- %g \\\\\n', mypois)
fprintf('P(X\\geq 1)&= %g \n', myres)
disp('\end{align*}')
l=1/3;
mypois=poisspdf(0,l);
myres=1-poisspdf(0,l)-poisspdf(1,l);
disp('\begin{align*}')
fprintf('P(X\\geq 2)&=1-P(X=0)=1- %g \\\\\n', mypois)
fprintf('P(X\\geq 2)&= %g \n', myres)
disp('\end{align*}')
#+end_src


#+RESULTS:
\begin{align*}
P(X\geq 1)&=1-P(X=0)-P(X=1)=1- 0.718924 \\
P(X\geq 1)&= 0.0438314 
\end{align*}
\begin{align*}
P(X\geq 2)&=1-P(X=0)=1- 0.716531 \\
P(X\geq 2)&= 0.0446249 
\end{align*}
\begin{align*}
P(X\geq 1)&=1-P(X=0)-P(X=1)=1- 0.718924 \\
P(X\geq 1)&= 0.0438314 
\end{align*}
\begin{align*}
P(X\geq 2)&=1-P(X=0)=1- 0.716531 \\
P(X\geq 2)&= 0.283469 
\end{align*}

#+end_solution


That is exported to 

\begin{solution}
The result is as follows
\begin{align*}
P(X\geq 1)&=1-P(X=0)-P(X=1)=1- 0.718924 \\
P(X\geq 1)&= 0.0438314 
\end{align*}
\begin{align*}
P(X\geq 2)&=1-P(X=0)=1- 0.716531 \\
P(X\geq 2)&= 0.0446249 
\end{align*}
\begin{align*}
P(X\geq 1)&=1-P(X=0)-P(X=1)=1- 0.718924 \\
P(X\geq 1)&= 0.0438314 
\end{align*}
\begin{align*}
P(X\geq 2)&=1-P(X=0)=1- 0.716531 \\
P(X\geq 2)&= 0.283469 
\end{align*}
\end{solution}
\end{document}

But I would like to have 
\begin{solution}[5cm]

How can I pass that parameter when exporting? Thanks
