[Scilab-users] Video Player in Scilab

[Shamika Mohanan]

Hello,

We are building a computer vision toolbox which requires developing a video
player.

We developed imshow using Matplot and then looped imshow over the number of
frames in the video to play the video. This method makes the video player
very slow. Is there any other way to play a video in Scilab using any
scripting tool/ GUI developer? Any leads would be appreciated.

[Scilab-users] vectorization issue

[paul . carrico]

Dear, 

I failed in using 100% vectorization in the following example (and I don't 
remember how to proceed) ; I spent a lot of time in testing things ... 


... what is the correct sentence for vecteur2 


Thanks for the help 


Paul

Re: [Scilab-users] unit tests and help generation for overloaded unary/binary operators

[Samuel Gougeon]

Hello Philippe,

AFAIR, XML filenames must not have the "%" character. Moreover, xml ids 
must exclude it as well.
So, if the xml id of the page is currently "%bigint_o_bigint", you 
should rather choose something like

"bigint_equal_bigint" instead.

help generation and unit tests are completely independent from each other.

Hi,

I'm writing a toolbox to handle "big integers" represented by a tlist

for bigint type  and overloaded unary and  binary operators (+,-,>,==,
...) for example %bigint_o_bigint  for bigint equality "=="  (see the
source code at the bottom of this message ). For each function I wrote,
I've created :

- a short help,  as a comment at the beginning of the *.sci file
- a test file "*.tst" placed in "/tests/unit_tests/" directory

I have some problems when I execute my builder.sce  :

if %bigint_o_bigint  function is stored in macros/%bigint_o_bigint.sci
and its unit test in tests/unit_tests/%bigint_o_bigint.tst  then I get
an error  during help generation (but unit_tests are OK) :

Check the following file :

Did you check it?

Or launch the following command :
-
exec("/home/roux/Documents/informatique/scilab/bigint/tests/unit_tests/bigint_o_bigint.tst");

Did you try it?

Re: [Scilab-users] scilab 6.0.0-beta-1 on Mac OS X El Capitan

[Paul Bignier]

Hello Peter,

Would you have more information about your issue?
Is it related to the reported bug 
?
Both betas work on my El Capitan, so it must be a configuration issue 
(external libs).


Regards,
Paul
