MathJSLab Calc is a scientific calculator-style Web application built on top of the `mathjslab` package. It starts as a prompt interpreter, like `mathjslab-app`, with a collapsible calculator keypad inspired by scientific calculator layouts. ## Development Install dependencies: ```sh npm install ``` Run the development server: ```sh npm run build:dev ``` Create a production build: ```sh npm run build ``` The build uses Eleventy for generated build configuration and Webpack for the browser bundle. SASS/SCSS is used for global styles and component Shadow DOM styles. ## Trademark Notes - [MATLAB®](https://www.mathworks.com/products/matlab.html) is a registered trademark of [The MathWorks, Inc.](https://www.mathworks.com/) - [MathJSLab](https://mathjslab.com/) is not affiliated, sponsored, or endorsed by [The MathWorks, Inc.](https://www.mathworks.com/) ## License > [MIT License](https://opensource.org/license/mit) > > Copyright © 2016-2024 [Sergio Lindau](mailto:sergiolindau@gmail.com), > [mathjslab.com](https://mathjslab.com/), > [ISBN 978-65-00-84828-1](https://grp.isbn-international.org/search/piid_solr?keys=978-65-00-84828-1) > > Permission is hereby granted, free of charge, to any person obtaining a copy > of this software and associated documentation files (the "Software"), to deal > in the Software without restriction, including without limitation the rights > to use, copy, modify, merge, publish, distribute, sublicense, and/or sell > copies of the Software, and to permit persons to whom the Software is > furnished to do so, subject to the following conditions: > > The above copyright notice and this permission notice shall be included in > all copies or substantial portions of the Software. > > THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR > IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, > FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
