$Using Math Subscript in an Expl3 Coffin$

Introduction

LaTeX is a powerful typesetting system that allows users to create complex mathematical equations and formulas. When working with coffins, a feature of the xcoffins package, it is possible to include math equations within the coffin. In this article, we will explore how to use math subscript in an expl3 coffin.

What are Coffins?

Coffins are a feature of the xcoffins package, which allows users to create complex layouts and arrangements of text and graphics. Coffins can be thought of as containers that can hold other LaTeX objects, such as text, images, and math equations. Coffins are particularly useful for creating complex layouts and arrangements of text and graphics.

Using Math Subscript in an Expl3 Coffin

When using the xcoffins interface for coffins, it is possible to put (more or less) complex math like an integral with limits in a coffin like this:

\NewCoffin \MytestCoffin
\SetHorizontalCoffin \MytestCoffin {
  $\int_{0}^{1} x^2 \, dx$
}

In this example, we create a new coffin called \MytestCoffin and set its horizontal content to be the math equation $\int_{0}^{1} x^2 \, dx$ . The math equation is typeset using the standard LaTeX math mode.

Using Expl3 to Create a Coffin

To create a coffin using expl3, we need to use the \NewCoffin command to create a new coffin, and then use the \SetHorizontalCoffin command to set its horizontal content. Here is an example:

\ExplSyntaxOn
\NewCoffin \MytestCoffin
\SetHorizontalCoffin \MytestCoffin {
  $\int_{0}^{1} x^2 \, dx$
}
\ExplSyntaxOff

In this example, we use the \ExplSyntaxOn command to enter expl3 mode, and then create a new coffin called \MytestCoffin using the \NewCoffin command. We then set its horizontal content to be the math equation $\int_{0}^{1} x^2 \, dx$ using the \SetHorizontalCoffin command. Finally, we use the \ExplSyntaxOff command to exit expl3 mode.

Using Math Subscript in an Expl3 Coffin with Limits

To use math subscript in an expl3 coffin with limits, we can use the following code:

\ExplSyntaxOn
\NewCoffin \MytestCoffin
\SetHorizontalCoffin \MytestCoffin {
  $\int_{0}^{1} x^2 \, dx$
}
\ExplSyntaxOff

Using Math Subscript in an Expl3 Coffin with Multiple Limits

To use math subscript in an expl3 coffin with multiple limits, we can use the following code:

\ExplSyntaxOn
\NewCoffin \MytestCoffin
\SetHorizontalCoffin \MytestCoffin {
  $\int_{0}^{1} \int_{0}^{1} x^2 \, dx \, dy$
}
\ExplSyntaxOff

In this example, we create a new coffin called \MytestCoffin and set its horizontal content to be the math equation $\int_{0}^{1} \int_{0}^{1} x^2 \, dx \, dy$ . The math equation is typeset using the standard LaTeX math mode, and includes multiple limits on the integral.

Conclusion

In this article, we have explored how to use math subscript in an expl3 coffin. We have shown how to create a new coffin using expl3, and how to set its horizontal content to be a math equation. We have also shown how to use math subscript in an expl3 coffin with limits, and how to use math subscript in an expl3 coffin with multiple limits. By following the examples in this article, you should be able to create complex math equations and formulas using the xcoffins package and expl3.
