Octave-control 包安装不起作用

Question

我已经从 ubuntu repo 成功安装了 octave 和 octave-control。

但是当我尝试使用它时出现以下错误。

enter octave:2> num = [ 1 2]  
num =

1   2

octave:3> den = [ 2 4 6]
 den =

 2    4   6

 octave:4> sys = tf(num,den)
  error: tfpoly: /usr/lib/x86_64-linux-gnu/octave/packages/control-2.8.3/x86_64-pc-linux-gnu-api-v50+/is_real_vector.oct: failed to load: /usr/lib/x86_64-linux-gnu/octave/packages/control-2.8.3/x86_64-pc-linux-gnu-api-v50+/is_real_vector.oct: undefined symbol: _ZNK5ArrayISsE17resize_fill_valueEv
