### Alias, surpress or declare with latex outputs...

July 08 2015
2 5

Hello,

i am trying to get a latex output which equals the displayed maple equations, where i am using alias/surpress or declare to shorten the dependencies of my derivatives. Whereas in Maple this looks how i want it to look like, i can not get the latex() command to apply the aliases. Instead it replaces the short forms with the long terms before creating the latex code. Is there anyway to get a latex output directly from the displayed math WITH alias?

2 small examples:

Both yield  $X \left( a,b,c \right)$ whereas i would like to get X. Simply substituing changes the partial differential symbol to "d" in the latex output and makes the equations unuseable, so this is no option i guess..

Thanks a lot for any suggestions!

### problems with export latex...

I'm new to mapleprimers and if I make some mistakes I apologize.

The problem I ran and on which I ask for help is that the command of maple latex I results in latex only the result of an arithmetic expression and the expression does not translate into latex itself. for example, the command latex (3 + 2) I 5 and not as a result from the translation in latex of 3 + 2. I also tried using the command inetrt form but did not succeed, I tried it with the quotes '' and even succeed. I also tried it with double quotes and with simple expressions funzioa eg latex ("(3 + 2) * 5") from me as a result  (3 + 2) * 5 '' but with more complex expressions: eg. latex("\""(2+1/(5))^(0)+(6/(9)*(((83-8)/(90))-15/(10)+(3/(9))/(2)) -6/(9))/(75/(100)*12/(9))"''") mi da

Error, Got internal error in Typesetting:-Parse:-Postprocess : "internal error: invalid object ""

Thanking for the help, Best regards

### Maple 18 and LaTex...

April 13 2015
1 2

Hey

As a lot of people before me I'm severely dissappointed my Maple's ability to export a .mw file to .tex.

The output looks horrible and even disappears off the side of the page in some places.

I've searched far and wide on the internet but it's difficult for me to understand the few, outdated, results I've dug up.

Is it completely impossible to get my hands on a good (or just working) Maple 18 to LaTex exporter? It's not possible for me to begin coding my own.

### how to change matrix brackets from [] to () ?...

March 07 2015

When I export to latex a matrix  <<a|b>,<c|d>>, the latex uses \begin[ and \end]

\left[ \begin {array}{cc} a&b\\ \noalign{\medskip}c&d\end {array} \right]
Is there a way to make Maple use () parenthesis instead of []? The screen display is not important for me in Maple, but I'd the latex to use () instead.  It will be nice if there is way to configure this. I looked but could not find an option.

### Export 3d plots as vector graphics...

February 09 2015

It seems a frequent issue that exported 3d plots are not shown as wished. I experience the same problem. Although I exported in the .eps format into a .tex latex-file the resulting .pdf-file shows a somewhat pixelated image of my 3d plot as if it was created in "Paint". Is there a solution for this in Maple13?

### Converting large symbolic Jacobian to LaTeX...

December 20 2014

I have generated an 8x8 Jacobian, containing a few variables and several zeros as elements. I would like to translate this to LaTeX code. How can I first simplify what I have, to make it tractable?

Here is the Maple code:

eq_1 := Lambda-mu*S-(beta*(H+C+C1+C2)*S+tau*(T+C)*S)/(S+T+H+C+C1+C2+C1M+C2M);
eq_2 := (-beta*(H+C+C1+C2)*T+tau*(T+C)*S)/(S+T+H+C+C1+C2+C1M+C2M)-(mu+mu[T])*T;
eq_3 := (beta*(H+C+C1+C2)*S-tau*(T+C)*H)/(S+T+H+C+C1+C2+C1M+C2M)-(mu+mu[A])*H;
eq_4 := (beta*(H+C+C1+C2)*T+tau*(T+C)*H)/(S+T+H+C+C1+C2+C1M+C2M)-(mu+mu[T]+mu[A]+lambda[T])*C;
eq_5 := lambda[T]*C-(mu+mu[A]+rho[1]+eta[1])*C1;
eq_6 := rho[1]*C1-(mu+mu[A]+rho[2]+eta[2])*C2;
eq_7 := eta[1]*C1-(mu+rho[1]+gamma)*C1M;
eq_8 := eta[2]*C2+rho[1]*C1M-(mu+rho[2]+gamma*rho[1]/(rho[1]+rho[2]))*C2M;
J := VectorCalculus:-Jacobian([eq_1, eq_2, eq_3, eq_4, eq_5, eq_6, eq_7, eq_8], [S, T, H, C, C1, C2, C1M, C2M]);

JQDFE := eval(J, [S = Lambda/(beta-mu[A]), T = 0, H = Lambda*(beta/(mu+mu[A])-1)/(beta-mu[A]), C = 0, C1 = 0, C2 = 0, C1M = 0, C2M = 0]);

Thanks.

### Latex typesetting of delayDotProduct...

December 16 2014
2 0

I would like to implement a rule for typeseting delayDotProduct in latex exports (in which this expressions appears in plain form). It corresponds to dot products of vectors/matrices with the "." operator. I tried to define

latex/Typesetting:-delayDotProduct:=proc(f1,f2,f3)
sprintf("{ {%s}{%s} }",cat(latex/print(f1)),cat(latex/print(f2)))
end proc:

which does not do the job.

Edit:

A related question: How can I make

D[1,1](x)(t)

produce x''(t) in latex output?

### Is there a clean and tidy way to export equations ...

November 01 2014

Hello everyone.

I have lots of lengthy equations in Maple that I don't want to waste time for rewritting them. I am looking for a clean and tidy way to export these equations from Maple and import them into a LaTeX or Word document.

As an example do it with the equation in the following file.

Example.mw

Many many thanks.

### how to make latex(1/2) produce a \frac{1}{2} in Ma...

August 02 2014

For some reason, Maple does not use \frac{}{} for things like 1/2 that can occur in an expression

restart;
expr:=1/2;
latex(expr);

1/2

This make the generated code not good looking. For example using this in Maple:

latex(diff(y(x), x)+y(x)*cos(x)-(1/2)*sin(2*x) = 0);

produces this latex when proccessed:

When the latex is put inside a display in the document.  This is terrible. Is there a way to tell Latex to use \frac{}{} for fractions?

### Output to Latex...

I run the command

> latex( '(3*p^4+3*p^2-2*p+1)/((1-p+p^2)*(1-3*p+3*p^2))' );

and I get

{\frac {3\,{p}^{4}+3\,{p}^{2}-2\,p+1}{ \left( 1-p+{p}^{2} \right)
\left( 1-3\,p+3\,{p}^{2} \right) }}

for some reason before every variable p I get a backslash and comman, \, and the frac{}{} command is always written as \frac {}{}, which isn't valid latex syntax, etc.  What's going on?
