装了个Octave

装了个Octave，用来做些题目。但是遇到了一些问题，结果不是很理想。
先是在Linux下装的。用的Gentoo，有些USE是去掉的。于是乎，最后装好的样子就是不能生成图形，也不能看help。不能生成图形是有心理准备的，因为我的Gentoo连X都没装，gtk 和 qt 也都是去掉的。不能生成help则是因为doc这个USE Flag被去掉了。如果加回去，则需要装很大一堆包，包括几个X的和几个Tex的，感觉太小题大做了。
于是，加上看着这个软件的计算功能还不错，本着用来代替Windows自带计算器的想法，准备装到Windows上去。我用的Windows8，使用了那个for VS2010的setup.exe来安装。装好后不能用…… 一查，发现这个在Windows8下还需要做点fix，需要在启动的时候加一个 -i --line-editing。 于是乎，加了，然后再打开。这下基本可以正常用了。可惜，想用于代替calc还是不太靠谱。原因无它，速度太慢了。打开慢，生成图像也慢。几十秒才能出结果，这简直无法接受。
但是我看别人好像并没有遇到“慢”的问题。不知道原因何在。是因为Windows8？还是因为我的jre不太对？我的jre装完后，只能执行java，一旦输入java -v 会直接告诉你不能生成VM，让人很囧。
我还有一台Windows8.1的机器，一会去试试看能否有改观。
