Re: IO package installation problem

[Hamed Shakouri]

Thank you for the clarification. I did so, and the package is now loaded.

But still xlsread(…) command doesn't work properly. "test" is a simple excel file with just one numeric cell.

The error message is:

>> xx=xlsread('test.xlsx')
Detected XLS interfaces: error: 'chk_jar_entries' undefined near line 38 column 22
error: called from
    __POI_chk_sprt__ at line 38 column 20
    getxlsinterfaces at line 139 column 23
    xlsopen at line 262 column 17
    xlsread at line 233 column 11

You are using octave 4.4.1 on windows.
Windows package include some pre-build octave-forge packages.
The io package is one of them.
The package that you want use should should be loaded before use.

On windows version 4.4.1

>> pkg list io
Package Name  | Version | Installation directory
--------------+---------+-----------------------
          io  |  2.4.11 | ...\share\octave\packages\io-2.4.11

>> pkg load io
>> pkg list io
Package Name  | Version | Installation directory
--------------+---------+-----------------------
          io *|  2.4.11 | C:\Octave\OCTAVE~2.1\share\octave\packages\io-2.4.11
"*" atter io indicates that io package is loaded and you can use it
