Several settings of the translation to LaTeX can now be adjusted according to preference, using the $\mathrm{latex}:-\mathrm{Settings}$ command or its synonym $\mathrm{LaTeX}:-\mathrm{Settings}$. These settings and the corresponding default values can be seen entering the command with no arguments or using the keyword query

$\mathrm{latex}:-\mathrm{Settings}\left(\right)$

$\left[\mathrm{cacheresults}=\mathrm{true}\,\mathrm{commabetweentensorindices}=\mathrm{false}\,\mathrm{invisibletimes}=''''\,\mathrm{leavespaceafterfunctionname}=\mathrm{false}\,\mathrm{linelength}=66\,\mathrm{powersoftrigonometricfunctions}=\mathrm{mixed}\,\mathrm{spaceaftersqrt}=\mathrm{true}\,\mathrm{usecolor}=\mathrm{true}\,\mathrm{usedisplaystyleinput}=\mathrm{true}\,\mathrm{useimaginaryunit}=\mathrm{I}\,\mathrm{useinputlineprompt}=\mathrm{true}\,\mathrm{userestrictedtypesetting}=\mathrm{false}\,\mathrm{usespecialfunctionrules}=\mathrm{true}\,\mathrm{usetypesettingcurrentsettings}=\mathrm{false}\right]$

The possible values of the right-hand sides and their meaning is as follows

cacheresults : all results by the internal latex subroutines are cached, for performance, so the translations are computed only once. However, if you are changing things in your worksheet that affect the way things are displayed, previously cached results may prevent you to get different LaTeX translations for the same input. To avoid caching results pass $\mathrm{cacheresults}=\mathrm{false}$. Alternatively, use the latex option forget, or the command $\mathrm{latex}:-\mathrm{Forget}\left(\right)$.

commabetweentensorindices : default value is false; if set to true, a comma between tensor indices is placed also in the LaTeX translation, so that they are displayed the same way they are on a Maple sheet.

invisibletimes : sets the string used to represent the product operator, by default " ". That matches the default of the LaTeX typesetting system where no spacing is placed between the operands of a product, so a*b is displayed $\mathrm{ab}$. To have a small space between the operands of a product you can use $\mathrm{invisibletimes}=''\backslash \backslash ,''$

leavespaceafterfunctionname : default value is false; if set to true no \! LaTeX negative spacing command will be placed between a function name, say $F$ and the large parenthesis \left( \right) surrounding the function's arguments.

linelength : default value is 66; it indicates the approximate length at which a line-break $''\backslash \backslash ''$ should be introduced when using the option breaklines.

powersoftrigonometricfunctions : default value is mixed; other possible values are textbooknotation and computernotation. With the value mixed, ${\sin \left(x+y\right)}^2$ is translated to LaTeX as \sin^2 (x + y), and upon compilation will look like ${\sin }^2\left(x+y\right)$. With the value textbook, in addition, inverse trigonometric functions are translated to LaTeX with the notation that uses the name of the corresponding trigonometric function power -1, so $\arcsin \left(x+y\right)$ is translated as \sin^{-1} (x + y). With the value computer the translation is an exact replica of what you see displayed on the Maple sheet.

spaceaftersqrt : default value is true; to insert or not a LaTeX small spacing command after a square root when it is an operand of a product.

usecolor : default value is true, so that colors in the worksheet are translated as such to LaTeX.

usedisplaystyleinput : default value is true, so that when using File > Export As > LaTeX all the input lines appears preceded by \displaystyle, i.e.: when compiling the .tex file, these lines are displayed with LaTeX math display style (the size of the fonts won't depend on the context).

useimaginaryunit : default value is the one shown by $\mathrm{interface}\left(\mathrm{imaginaryunit}\right)$, that in Maple is the capital letter I. This setting can be used to indicate the use of a different symbol when translating to LaTeX.

useinputlineprompt : can be true or false, to put or not a prompt at the beginning of Maple input lines when using File > Export As > LaTeX. When the Maple sheet was created as a worksheet, $\mathrm{interface}\left(\mathrm{format}\right)=''worksheet''$ and so the default value of useinputlineprompt is true. Otherwise, when it started as a document, $\mathrm{interface}\left(\mathrm{format}\right)=''document''$ and the value of useinputlineprompt is by default false. You can use useinputlineprompt to override these default values.

userestrictedtypesetting : default value is false; if set to true, only a restricted form of typesetting, like the one used in the input lines of the Maple help pages, is used when translating to LaTeX.

usespecialfunctionrules : default value is true; if set to false, no typesetting for the notation of mathematical functions is used.

usetypesettingcurrentsettings : default is false; if set to true the Typesetting rules set in the Maple worksheet are not overridden by latex.

The section latex:-Tips present several recommendations to get an optimal translation when exporting Maple sheets using File > Export As > LaTeX. Among the most relevant ones:

In the worksheet, before exporting, remove all or selectively some of Maple's input, while keeping all of Maple's output and corresponding equation labels, by respectively using the menus View > Show/Hide Contents > Input or Edit > Delete Element. This is particularly useful to produce LaTeX mathematical documents that entirely or partially hide their computer algebra origin.

In the worksheet, select any mathematical expression written using Maple syntax that appears within the text (e.g. Int(f(x), x)), or as Maple input and use Format > Convert To > 2-D Math Nonexecutable (or, alternatively, right-click (Command-click, on Mac) and select Convert To > 2-D Math Nonexecutable) to produce a textbook mathematical display of that expression, that will then appear as such in the LaTeX exported document.

In the resulting filename.tex file, adjust the new automatic line-breaking of math formulas by placing $\mathrm{\backslash \backslash }$ wherever you want an additional line-break, or enclosing a formula's subexpression between $\left\{\right\}$ to avoid its automatic line-breaking.

Set several preferences regarding how to perform the LaTeX translation using the latex:-Settings command. To see the different settings and their current value enter $\mathrm{latex}:-\mathrm{Settings}\left(\right)$.
