Hi,

This toolbox is not visible from the ATOMS GUI. It has no loader (i guess that the builder
should be run and then removed before uploading the built toolbox).

Scilab 5.4.1 now includes dct() and idct functions.

The radonc() called from radon() is unavailable (likely needs a gateway that is not
distributed):
->[R,xp] = radon(I,theta);
 !--error 4 
Undefined variable: radonc
at line      19 of function radon called by :  
[R,xp] = radon(I,theta);

Regards
Samuel

The author of this module received an e-mail from our part. As indicated here
(http://wiki.scilab.org/ATOMS#From_5.3_to_5.4_family), he must create a 5.4 version to
make it available for the 5.4 family, before anything else.

Hi,
The ATOMS facility provides full versionning features. This is a great improvement w.r.t.
to previous system, with which former versions of a module were not tagged as is, making a
mess.
This module looks to be a trial, since you re-published it as a new distinct module
https://atoms.scilab.org/toolboxes/IPT2,
ignoring versioning possibility. 
Could you please cancel the present one? At least, please cancel all its files, that could
be a way to tell "This module is not active".
Thanks
Samuel

Hi,
I followed your link "https://atoms.scilab.org/toolboxes/IPT2"
downloaded and installed 
the zip-file "IPT2-2.0.1-src.zip" on Scilab 5.4.1.
But as I wanted to use the radon transform, the following error mesage was show in the 
command window:

Undefined variable: radonc
at line      19 of function radon called by :  
[R,xp] = radon(I,theta);
at line       5 of exec file called by :    
orial\Scilab_Code\Test_IPT2.sce', -1

What's the problem? Is a bug also in the new file?
Or isn't it possibles to use the radon transform for Scilab 5.4.1 at all?

Thanks
Tobias
