solver for system of linear equation in java for large matrices (finite element program)

hi friends!

I am a student for second degree at mechanical engineering and i develop a finite element code at java.

i looking for efficiency solver and fast for large, sparse , symmetric and positive define matrices .

i used in jblas but i encounter in problem when the matrix has high condition number(ill condition number) and i get error for singular matrix while in mathematica i succeed to solve that system without problems...

do you knows for good solver and fast solver package in java can i use for solving that system?

thanks!

I have no personal experience, but you might check out EJML. Otherwise, Googling for another suitable package is recommended.

Also have a look at Apache Commons Math and/or Weka
