    Default 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.
