Which MATLAB alternative is open source?

GNU Octave, Scilab, Python + Jupyter are open source.

Are compatible (reverse-engineered) alternatives legal?

Yes. Tools marked Compatible are independent re-implementations built to open the same files or run the same software. They do not contain the original program's code. They are not cracked or pirated copies, which we never recommend.

关于“兼容”工具： 独立、合法的重新实现，能打开相同的文件或运行相同的软件。不是破解版。

常见问题

有没有免费的 MATLAB 替代品？

Yes. GNU Octave is a strong free option for running most matlab scripts unchanged. Other choices include Scilab, Python + Jupyter.

哪款 MATLAB 替代品是开源的？

GNU Octave, Scilab, Python + Jupyter 是开源的。

兼容（逆向工程）替代品合法吗？

合法。标为“兼容”的工具是独立的重新实现，用于打开相同的文件或运行相同的软件，不包含原程序的代码。它们不是破解版或盗版——我们从不推荐那些。
