[Scilab-users] Antwort: Re: [EXTERNAL] Problem with solving this elegantly

[Pascal Buehler]

not really in this case, here you have already the eigenvalues lambda1=7 
and lambda2=3.
Now for lambda1, insert the number to the matrix, where sigmaxx =-1, 
sigmayy =5 and tauxy=4 already known is, as a stress tensor
 you will get two linear equation like

-8*v1x+4*v1x=0
4*v1x-2*v1y=0

normaly an trivial solution, but non of the sovers gave me the correct 
answer?

Maybe I’m mistaken, but the first matrix sounds like an eigenvalue 
problem, isn’t it ?
(I’m not familiar with German …
 
If so, did you tried “eigs”?

Objet : [EXTERNAL] [Scilab-users] Problem with solving this elegantly
 
Hello there, i searched in scilab a macro, that can solve me this in an 
elegantly matrix way? 

I've really searched something similar to A*X=0, but no linsolver gave me 
the right answer?
