This is memo only for me during the process of numerical computing.

1.gnuplot与c语言画图：

open ~/.bash_profile

---------------------------

打开记事本，预设程序路径问题。比如c语言导用gnuplot

export PATH=/Applications/gnuplot.app:/Applications/gnuplot.app/bin:$PATH

保存后，需要更新。如下

source ~/.bash_profile

画图有两个工具：AquaTerm和x11。

 使用x11的场合，需要在bash_profile中添加

export GNUTERM=x11

2.安装macports

You should download the pkg install softwares from official website.

预设程序路径问题

export PATH=/opt/local/bin:/opt/local/sbin:$PATH

export MANPATH=/opt/local/share/man:/opt/local/man:$MANPATH
