If the LaTeX syntax is not correct or not included in the COMSOL Multiphysics software, the equation preview is empty, but no error appears. Also, for symbols in math mode, surround the LaTeX syntax with $ to indicate that the text inside of the $ signs is LaTeX when used as an annotation text, for example.

Invoke the array environment (see Note below)

End the array environment (see Note below)

The \left and \right commands must be used in pairs to provide flexible delimiters that fit the formula inside. Put the desired delimiter — ( and ), for example — immediately after the \left and \right commands. For example, \left( \frac{x}{y} \right) provides x/y as a fraction within parentheses that fit the expression’s size.
|
The \begin and \end commands must be used in pairs to mark the beginning and end of an environment. The only supported environment is the array. For example, \begin{array}{clcr} 1 & 2 & 3 \\ 4 & 5 & 6\end{array} creates a matrix with 2 rows and three columns.

Use the syntax \frac{numerator}{denominator} to create a fraction. For example, the expression \frac{n!}{k!(n-k)!} produces the following output:

Use the syntax \sqrt[order]{expression} to create a root surrounding an expression. The [order] argument is optional; without it, the syntax produces a square root. For example, \sqrt[n]{1+x^2} produces the following output:

The \textsuperscript and ^ syntax alternatives are identical for creating superscripts. Likewise, \textsubscript and _ are identical for creating subscripts.
