Python中的Numpy、SciPy、MatPlotLib安装与配置

Python安装完Numpy，SciPy和MatplotLib后，可以成为非常犀利的科研利器。本人搜索诸多安装教程后才找到正确的资源来配置，共享下。

    安装环境：64位python2.7

    下载http://pan.baidu.com/s/1c1Phqko中三个库的exe,因为MatplotLib的使用需要以Numpy的支持，所以先点击安装Numpy，其次是Scipy,最后是MatplotLib，一路点击next即可。

     安装时如果出现了Python 2.7 was not found in the registry的错误信息，则新建一个register.py，复制下面代码运行，输出：Python 2.7 is already registered就代表问题已解决。
