Dear Phiip,

Sorry, for taking your time.
I tried several times to install I/o package version .11
I had Java (64 bits) already installed.
I tried >> pkg install io
..
But after all when trying to read an xls file I see this error message:
warning: Functions for spreadsheet style I/O (.xls .xlsx .sxc .ods .dbf .wk1
etc.) are provided in the io package. See
<https://octave.sourceforge.io/io/>.

 and nothing is read.
Would you help me come up with this?
Thank you,
Hamed.

Did you first do
pkg load io
?

Not inside the Octave, but from the webpage, and I put it in the current
folder so that it would be found by "pkg install".
Isn't it sufficient?

After installing any package, to use the functions in it, you need to
invoke in Octave `pkg load package_name`.

Dear Nir,
Thank you for the information.

pkg install io-2.4.11.tar.gz

warning: (Automatic loading of spreadsheet I/O Java classlibs failed)
For information about changes from previous versions of the io package,
run 'news io'.
So, the package is not installed yet!
How this can be solved?

Please keep copying the mailing list.

As long as `pkg install` gives no `error` message, the installation was
presumably more or less successful. So you should follow with `pkg load io`
and see if the functionality you need works.

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

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.

I myself have never used xlsread.

After some googling, 
I think that something is wrong with Java (Oracle JRE).

If you install MS-Excel(32 bit) on your PC, you can access xlsx via windows and MS-Excel internally.
You can do the above when you load the windows package in addition to the io package

(You can check your Excel is 32 or 64 bit by task manager.)
