My sci lab is working fine .but on your fossee site there is "sci lab arduino" icon.so if i try to access it gives error.

Yes. The problem will be fixed soon. Please keep checking the link. Thank you for helping us identify it.

The problem has been fixed.

Thank you very much.but are there any spoken tutorials for scilab arduino.i didnt find any. is there any workshop for scilab as well as for scilab-arduino interfacing.?

There are no spoken tutorials as such for Scilab-Arduino. However we have written a book on how to use Scilab with arduino. See the link https://scilab-arduino.fossee.in/downloads We have spoken tutorials on Arduino though. See http://spoken-tutorial.org/tutorial-search/?search_foss=Arduino&search_language=English

There is no upcoming workshop on scilab-arduino for now. In case if we host one, it will be notified on fossee.in. So keep checking fossee.in regularly to know about upcoming workshops and other activities.

Thank you very much for the information.i have seen spoken tutorials on scilab.they are very nice.okay will wait for the workshop on scilab.  but one problem in Xcos is the demos are not working related to electrical engineering.

You are asking a different question. I think your question is similar to this http://forums.fossee.in/question/133/scilab-552-xcos/
If it is, please discuss/reply there. If it is not, please post a fresh question. This will help in future to track questions.

Ok
