VecTcl - numerical math in Tcl
官網的介紹如下：
This package provides a numerical array extension for Tcl with support for vectors, matrices and higher-rank tensors of integers, floating point and complex numbers. It has builtin support for basic array shaping, slicing and linear algebra subroutines and is designed to integrate seamlessly with Tcl. The user interface consists of a single command,
vexpr, which acts as an expression evaluator similar to expr. The language supported by vexpr is inspired by Matlab, which closely models the language used by textbook math.
很有趣的一個套件，如果執行的時候夠高效的話，應該對於一些數學運算有幫助。
