我刚刚安装了octave-geometry包,并尝试调用:
drawShape('rect', [20 20 40 10 pi/3]);
结果是:
error: 'rectAsPolygon' undefined near line 78 column 21
error: called from
drawShape at line 78 column 19
我正在运行Linux Mint 17(Qiana)。最初,我通过apt-get安装,它使用octave 3.8,并得到了类似的结果。所以,我安装了八度版本4.0,采取以下路线:
sudo apt-add-repository ppa:octave/stable
GUI安装好了,但我仍然无法使用几何包。
>> pkg load geometry;
>> ver
