### Solve Symmetric System

Posted:

**Thu Jul 04, 2013 4:08 am**Hi, I have a largish (2000*2000) dense system to solve, but it is symmetric (not positive definite though). How would you suggest I deal with this? I can fill both sides of the matrix on the host before running sgesv, or I could use ssyr2k with an identity matrix to fill one side give the other, or something else? I'm looking for the fastest method. Thanks.
