之前介紹 Python 在複雜網路模擬實驗的應用時，曾提到用 Matplotlib 來繪製該實驗的圖表。其模仿 Matlab 的繪圖功能，用起來方便，所繪製的圖也在水準之上。有圖有真相，這就秀秀用 Matplotlib 為該實驗繪製的兩張圖表：
模擬複雜網路，也可以套用 Agent-based modeling 架構。不過諸如網路的群聚度（clustering coefficient, C）及網路特徵的路經長度（characteristic path length, L）等統計數據計算需耗費的時間，隨著網路的規模成長很快，所以不適合運作太頻繁。但我們卻得靠這些統計數據來判斷網路是否收斂、試驗是否該終止了，想試驗各個參數排列組合時，更是雪上加霜。
SciPy is open-source software for mathematics, science, and engineering. It is also the name of a very popular conference on scientific programming with Python.
The Scientific Graphics Toolkit (SGT) facilitates easy development of platform independent, Java applications to produce highly interactive, flexible, publication quality, object oriented graphics of scientific data. Features include user settable or auto

作科學研究常需要作些計算，可以幫我們作這些運算的軟體很多，其中最讓我印象深刻的是 Mathematica 及 Matlab 。它們用起來方便，功能更是不在話下，但就是要花錢買，而且還不便宜。
