[Octave-bug-tracker] [bug #58667] [octave forge] (control) Some scripts in the control package need to be updated

[董瑞军]

Follow-up Comment #8, bug #58667 (project octave):

Hope this helps. I uninstalled and reinstalled Octave-5.2.0. This is my
restallation record. 
1. Run octave-5.2.0_1-w64-installer. 
2. A message appears, indicating that the installer cannot find the Java
Runtime Environment on my system. Continue installation? Choose yes. 
3. After several times of Next, change the destination folder from
C:\Octave\Octave-5.2.0 to E:\Octave\Octave-5.2.0. Then click install. 
4. After the installation is complete, run GNU Octave. 
5. Run the following command:

z=[         0      -0.0013
    0.0010    0.0479
    0.0020    0.1877
    0.0030    0.4118
    0.0040    0.7060
    0.0050    1.0640
    0.0060    1.4912
    0.0070    1.9666
    0.0080    2.4932
    0.0090    3.0664
    0.0100    3.6786
    0.0110    4.3286
    0.0120    5.0134
    0.0130    5.7267
    0.0140    6.4674
    0.0150    7.2320
    0.0160    8.0178
    0.0170    8.8276
    0.0180    9.6546
    0.0190   10.4962
    0.0200   11.3544
]
data=iddata(z(:,2),ones(21,1),.001);sys=tfest(data,2,0)

6. Get the following error message:

error: 'is_matrix' undefined near line 50 column 9
error: called from
    __iddata_dim__>__experiment_dim__ at line 50 column 3
    __iddata_dim__ at line 29 column 12
    iddata at line 124 column 13

7. Run pkg load control. This time the above problem was solved. 
8. However, the following command history reminds me that in my first
installation, running pkg load control also went wrong which I cannot
reproduce it now. I had to manually add the path and modify is_matrix to
ismatrix in the iddata_dim script to make iddata available.
