我在Ubuntu 18上安装Octave的Communications软件包时遇到问题，我从安装liboctave 开始
sudo apt-get install liboctave-dev
然后我安装了通信包的depency包：
pkg install control-3.1.0.tar.gz
pkg install signal-1.4.0.tar.gz
pkg install communications-1.2.1.tar.gz
当我到达第三个命令时，它给了我这个错误，这可能是由于使用了不推荐使用的代码：

有人能帮忙吗？
也许您可以尝试使用以下命令从ubuntu的终端安装communications package。
sudo apt-get update
sudo apt-get install octave-communications
检查一下：
>> pkg list
Package Name | Version | Installation directory
----------------+---------+-----------------------
communications *| 1.2.1 | /usr/share/octave/packages/communications-1.2.1
control *| 3.2.0 | /home/hugo/octave/control-3.2.0
signal | 1.4.1 | /home/hugo/octave/signal-1.4.1
然后尝试使用它，它就会工作：>> pkg load communications
似乎已经进行了一些重构，需要更新通信包。理论上，这似乎是一个简单的解决方案。您可以联系Mike Miller(软件包页面中指定的维护人员：https://octave.sourceforge.io/communications/index.html(并告知他们，或者您可以尝试自己重命名上述函数。
