Subject: [Scilab-Dev] Problem to create file .Jar, is getting empty
Message-ID: <CALbJxT47s59R6a=8JA-ce_bRk8wGUwumd4KAm2A5z-mcs-75Xg@mail.gmail.com>

I have a doubt.
How do you create .jar used in help.

When I have create, the .jar file is getting empty

I do this: [1]Help_from_sci, [2]Xmltojar

// first generate the .xml files
Help_from_sci (dirname, helpdir);

// then generate the .jar file
My_english_help_dir = my_module_path + '/ help / en_US';
My_english_help_title = 'toolbox_test';

Xmltojar (my_english_help_dir, my_english_help_title, 'en_US');

Add_help_chapter (my_english_help_title, my_module_path + "/ jar");
Del_help_chapter (my_english_help_title);

Subject: [Scilab-Dev] variable damaged if treated in functions
Message-ID: <1496763361930-4036546.post@n3.nabble.com>

Hello,
the size of a variable changed strangely.
If I put the sub-function code in the function body the code works.
ruin_demo.sce <http://mailinglists.scilab.org/file/n4036546/ruin_demo.sce>

here the example with code in body (not in a function)
ruin_demoSane.sce
<http://mailinglists.scilab.org/file/n4036573/ruin_demoSane.sce>  

and again the code in function where the variable size changes.
ruin_demo.sce <http://mailinglists.scilab.org/file/n4036573/ruin_demo.sce>

Hello Ritveeka,

The `sum(in)` expression discard any matrix / vector combination of the `in` variable. Reusing
`clrs(:)` there will no update the clrs accordingly to the new inputs.
