问题描述
我尝试了几个命令将软件包optim安装到Ubuntu 16.10中的Octave中以使用功能xcorr，但是我不幸失败了.
I tried several commands to install the package optim into my Octave in Ubuntu 16.10 to use the function xcorr, but I miserably failed.
其中一些命令是:
- sudo apt-get install octave-optim
- sudo apt-get install liboctave-dev
- sudo apt-get install octave-signal
- sudo apt-get install octave-pkg-dev
有人可以向我解释一下，还是有人知道如何在Ubuntu 16中安装软件包?运行上述命令后，我重新启动了Octave，但命令xcorr()仍返回错误:
Can somebody explain me or does somebody know how to install the packages in Ubuntu 16?After running the above-mentioned commands, I restarted Octave but the command xcorr() was still returning the error:
不幸的是，"pkg"返回:
Unfortunately, 'pkg' returns:
推荐答案
请先在Octave命令提示符下键入pkg load signal，因为您已经安装了它.要在每次启动Octave时自动加载它，请创建〜/.octaverc文件，并在文件内部添加行pkg load signal.
Please type pkg load signal in the Octave command prompt, as you have already have it installed. To auto-load it everytime you start Octave, create ~/.octaverc file and add the line pkg load signal inside the file.
如果将来尚未安装所需的pkg，则需要使用pkg install -forge <pkgname>进行安装，例如pkg install -forge io.同样，您将需要如前所述加载它.
If in future, the pkg that you need is not currently installed, you will need to install it with pkg install -forge <pkgname> e.g. pkg install -forge io. Similarly, you will need to load it as described earlier.
希望有帮助.
