If you also encouter this latex error: Undefined control sequence. <recently read> \multirow , i think this tutorial will help you.
How does this error occur?
The main reason is missing package:multirow
To solve this error, you should use \usepackage{multirow}
Here is an example:
- \documentclass[preprint,12pt]{elsarticle}
- \usepackage{amssymb}
- \usepackage{amsmath}
- \usepackage{float}
- <span style="color: #008080;">\usepackage{multirow}</span>
- \usepackage{graphicx}
- \journal{Knowledge-Based Systems}
- \begin{document}
- \begin{frontmatter}
