when executing a src block with latex construct, display problem because of +

[Uwe Brauer]

Hi 

I have the following src block

#+begin_src matlab :results output raw :exports code  :eval never-export
addpath /home/oub/ALLES/HGs/Matlab-init/Statistic
sens=0.7;
spec=0.95;
aspec=1-spec;
prob=0.1;
sal=1-prob;
[bp,bpinv,bn,bninv]=mibayes(sens,spec,prob);
disp('\begin{align*}')
disp('P(\text{Covid19}|\text{+})&=\frac{P(\text{+}|\text{Covid19})P(\text{Covid19})}{P(\text{+}|\text{Covid19})P(\text{Covid19})+P(\text{+}|\text{No-Covid19})P(\text{No-Covid19})}\\')
fprintf('P(\\text{No-Covid19}) &= 1- P(\\text{Covid19}) = 1-%g=%g\\\\ \n',prob,sal)
fprintf('P(\\text{+}|\\text{No-Covid19}) &= 1-    P(\\text{-}|\\text{No-Covid19}) = 1-%g=%g \\\\ \n',spec,aspec)
fprintf('&=\\frac{%g \\cdot %g}{%g\\cdot%g + (1-%g)\\cdot %g}\\\\ \n',spec,prob,spec,prob,spec,sal)
fprintf('P(\\text{Covid19}|-)&=%g \\\\ \n', bp);
fprintf('P(\\text{No-Covid19}|+)&=1-P(\\text{Covid19}|+)=%g \\\\ \n', bpinv);
disp('\end{align*}')
#+end_src

That is exported to 
#+RESULTS:
\begin{align*}
P(\text{Covid19}|\text{+})&=\frac{P(\text{+}|\text{Covid19})P(\text{Covid19})}{P(\text{+}|\text{Covid19})P(\text{Covid19})+P(\text{+}|\text{No-Covid19})P(\text{No-Covid19})}\\
P(\text{No-Covid19}) &= 1- P(\text{Covid19}) = 1-0.1=0.9\\ 
P(\text{+}|\text{No-Covid19}) &= 1-    P(\text{-}|\text{No-Covid19}) = 1-0.95=0.05 \\ 
&=\frac{0.95 \cdot 0.1}{0.95\cdot0.1 + (1-0.95)\cdot 0.9}\\ 
P(\text{Covid19}|-)&=0.000139982 \\ 
P(\text{No-Covid19}|+)&=1-P(\text{Covid19}|+)=0.99986 \\ 
\end{align*}

Now in my org mode file, the lines between the +

\text{+})&=\frac{P(\text{+}|\text{Covid19})P(\text{Covid19})}{P(\text{+}|\text{Covid19})P(\text{Covid19})+P(\text{+}|\text{No-Covid19})P(\text{No-Covid19})}\\ 

Get a overstrike.

How can I avoid that?

Thanks and regards

Customize `org-src-lang-modes' adding ` ("matlab" . octave)'.

Thanks, it did not help. To make this clear the problem occurs in the
result block, not in the source block. 



 That is exported to 
 #+RESULTS:
 \begin{align*}
 P(\text{Covid19}|\text{+})&=\frac{P(\text{+}|\text{Covid19})P(\text{Covid19})}{P(\text{+}|\text{Covid19})P(\text{Covid19})+P(\text{+}|\text{No-Covid19})P(\text{No-Covid19})}\\
 P(\text{No-Covid19}) &= 1- P(\text{Covid19}) = 1-0.1=0.9\\ 
 P(\text{+}|\text{No-Covid19}) &= 1-    P(\text{-}|\text{No-Covid19}) = 1-0.95=0.05 \\ 
 &=\frac{0.95 \cdot 0.1}{0.95\cdot0.1 + (1-0.95)\cdot 0.9}\\ 
 P(\text{Covid19}|-)&=0.000139982 \\ 
 P(\text{No-Covid19}|+)&=1-P(\text{Covid19}|+)=0.99986 \\ 
 \end{align*}


I attach a screenshot just in case

Oh, I misunderstood.

The result looks like latex. So why not use `:results output latex' ?

I tried that also, then however the result is 
#+RESULTS:
#+begin_export latex
\begin{align*}
P(\text{Covid19}|\text{+})&=\frac{P(\text{+}|\text{Covid19})P(\text{Covid19})}{P(\text{+}|\text{Covid19})P(\text{Covid19})+P(\text{+}|\text{No-Covid19})P(\text{No-Covid19})}\\
P(\text{No-Covid19}) &= 1- P(\text{Covid19}) = 1-0.1=0.9\\ 
P(\text{+}|\text{No-Covid19}) &= 1-    P(\text{-}|\text{No-Covid19}) = 1-0.95=0.05 \\ 
&=\frac{0.95 \cdot 0.1}{0.95\cdot0.1 + (1-0.95)\cdot 0.9}\\ 
P(\text{Covid19}|-)&=0.608696 \\ 
P(\text{No-Covid19}|+)&=1-P(\text{Covid19}|+)=0.391304 \\ 
\end{align*}
#+end_export

That is ok for displaying, but if I now want also to export this org
file to latex, the align construct is not exported, sigh. 

As the great philosopher M. Jagger said:

Uwe,

You used `:exports code :eval never-export' (from an earlier posting). 

I think you want `:exports both :eval never-export' to keep babel from removing the results.

Thanks very much, that was the essential bit of code. Solved!
