Gauss-Seidel Solver for Python 2.7 -

-

is there python 2.7 package contains gauss-siedel solver systems more 3 linear algebraic equations containing more 3 unknowns? simple example of sort of problem solve given below. if there no templates or packages available, possible solve in python? if please advise on best way of going it. thanks.

an example of 3 linear algebraic equations 3 unknowns (x,y,z):

x - 3y + z = 10

2x + 5y + z = 4

-x + y - 2z = -13

after bit of searching around found solution use numpy.linalg.solve command. command uses lapack gesv routine solve problem; not sure iterative technique uses.

here code solve problem if interested: 

a = np.array([[1,-3,1],[2,5,1],[-1,1,-2]]) b = np.array([10,4,-13])  x = np.linalg.solve(a, b)  print x  print np.allclose(np.dot(a, x), b)      # check solution found

PHPMotion implementation - URL based videos (Hosted on separate location) -

i have implement video collection website users of specific isp. site hosted on public web-server movies hosted on local isp server. user of isp + general visitors can see available movies; isp's users able play them. player on site point url of local machine ( http://192.x.x.x/movies/mymovie.mov ) private class (192.x.x.x) accessible isp user. question: possible phpmotion script? or need custom work. if possible, can please suggest available mods? phpmotion require modifications able handle this. uploading, conversion, thumbnail generation, , playback pretty static in phpmotion. really though, rather modding entire upload , conversion process, if created quick custom form add entries phpmotion database (maybe include thumbnail upload), tweaked playback paths, should go on phpmotion side of things. assume had videos in format player handle (such flv or mp4).

javascript - Using Windows Media Player as video fallback for video tag -

getting video play cross platform using example video.js bit of fuss. in days when video should embedded use embed windows media player, work out of box on windows. since it's today old ie on windows doesn't support video tag experimented using windows media player fallback, , work well. what wonder here is, why haven't else solution? have missed something? code small, there's no flash files, cross domain issues or need of server working. works. so before develop further , add custom control , subtitles support wonder say. the code looks this: <video id="myvideo" style="width:640px; height: 360px;" autoplay data-wimpsource="http://esd.volvocars.com/dc/cdn/video/birds-on-a-wire.mp4"> <source src="http://esd.volvocars.com/dc/cdn/video/birds-on-a-wire.mp4" type="video/mp4" /> <source src="http://esd.volvocars.com/dc/cdn/video/birds-on-a-wire.webm" type="video/webm" />

i'm trying clean default implementation of accountcontroller.cs comes out of box in new mvc5/owin security implementation. have modified constructor this: private usermanager<applicationuser> usermanager; public accountcontroller(usermanager<applicationuser> usermanager) { this.usermanager = usermanager; } also, have created lifetime manager unity looks this: public class httpcontextlifetimemanager<t> : lifetimemanager, idisposable { private httpcontextbase _context = null; public httpcontextlifetimemanager() { _context = new httpcontextwrapper(httpcontext.current); } public httpcontextlifetimemanager(httpcontextbase context) { if (context == null) throw new argumentnullexception("context"); _context = context; } public void dispose() { this.removevalue(); } public override object get
