This command converts a LaTeX expression to MathML, and optionally further processes it into a Maple expression.

By default, the command just converts the string to MathML. To convert the expression to a Maple expression, use the output = maple option. The default is output = mathml. This can be used if MathML is the intended final format, or if you want more control over how the MathML is imported into Maple, as shown in the final example below.

$L≔''\backslash \backslash cos\; (2\backslash \backslash theta)\; =\; \backslash \backslash cos^2\; \backslash \backslash theta\; -\; \backslash \backslash sin^2\; \backslash \backslash theta''\:$

$\mathrm{mml}≔\mathrm{MathML}:-\mathrm{FromLatex}\left(L\right)$

$\mathrm{mml}≔''$ \cos \&\#x00028;2\mathrm{\&\#x003B8;}\&\#x00029;\&\#x0003D;{\cos }^2\mathrm{\&\#x003B8;}\&\#x02212;{\sin }^2\mathrm{\&\#x003B8;}$''$

$\mathrm{MathML}:-\mathrm{Import}\left(\mathrm{mml}\,\mathrm{source}=''calculator''\right)$

$\cos \left(2\mathrm{\theta }\right)={\cos \left(\mathrm{\theta }\right)}^2-{\sin \left(\mathrm{\theta }\right)}^2$

$\mathrm{MathML}:-\mathrm{FromLatex}\left(L\,\mathrm{output}=\mathrm{maple}\right)$

$\cos \left(2\mathrm{\theta }\right)={\cos \left(\mathrm{\theta }\right)}^2-{\sin \left(\mathrm{\theta }\right)}^2$

$L≔''\backslash \backslash frac\{n!\}\{k!(n-k)!\}\; =\; \backslash \backslash binom\{n\}\{k\}''\:$

$\mathrm{mml}≔\mathrm{MathML}:-\mathrm{FromLatex}\left(L\,\mathrm{output}=\mathrm{maple}\right)$

$\mathrm{mml}≔\frac{n!}{k!\left(n-k\right)!}=\left(\genfrac{}{}{0ex}{}{n}{k}\right)$

$L≔''\backslash \backslash frac\{\backslash \backslash frac\{1\}\{x\}+\backslash \backslash frac\{1\}\{y\}\}\{y-z\}''\:$

$\mathrm{mml}≔\mathrm{MathML}:-\mathrm{FromLatex}\left(L\,\mathrm{output}=\mathrm{maple}\right)$

$\mathrm{mml}≔\frac{\frac{1}{x}+\frac{1}{y}}{y-z}$

$L≔''\backslash \backslash frac\{\backslash \backslash frac\{1\}\{2\}+\backslash \backslash frac\{1\}\{3\}\}\{4-5\}''\:$

$\mathrm{mml}≔\mathrm{MathML}:-\mathrm{FromLatex}\left(L\right)$

$\mathrm{mml}≔''$ \frac{\frac{1}{2}\&\#x0002B;\frac{1}{3}}{4\&\#x02212;5}$''$

$\mathrm{iex}≔\mathrm{MathML}:-\mathrm{Import}\left(\mathrm{mml}\,\mathrm{source}=''calculator''\,\mathrm{output}=''inert''\right)$

$\mathrm{iex}≔\frac{\frac{1}{2}+\frac{1}{3}}{4-5}$

$\mathrm{value}\left(\mathrm{iex}\right)$

$-\frac{5}{6}$

The MathML[FromLatex] command was introduced in Maple 2025.
