Thank you for your correct answer.
I will try it again later today.
Before that I need your further confirmation.
1. The directory where octave is the place for locating bundle.2.7.1.zip file.
Is this right?
2. This is an ambiguous one whenever I tried. At dos promt of octave, so I have to run command listed. Do I need to change the current directory to the directory where bundle.zip is located?
Like ; cd hwang
Where hwang is the directory having the bundle zip file.
And execute the command at this changed directory not other directory.
Is this right process to activate symbolic?
Let me know your nice answer!
