Re: [OctDev] new package ncArray 1.0.0

[Alexander B. <bar...@gm...>]

Sorry for poor spelling in my last email. The email was sent
inadvertently before I could check it.
Source packages are here:

http://modb.oce.ulg.ac.be/mediawiki/upload/Alex/ncArray/ncarray-1.0.0.tar.gz
http://modb.oce.ulg.ac.be/mediawiki/upload/Alex/ncArray/ncarray-html.tar.gz

Can somebody update the server?
Best regards,
Alex
