Set boundary condition on a singular matrix

Hey folks,

i am a newbie in using the MKL.

If I build up a stiffness matrix on a FEM problem the stiffness matrix is singular. To solve a problem - no matter which one - you have to make the siffness matrix nonsingular/regular by inserting a boundary condition on the equation A x = b.

Does somebody of you know if there is a pre-written *.f or *.f90 routine for inserting a boundary condition in a  CSR format of the BLAS/PARDISO package?

Do I have to write it by my own? :-)

Thanks,

Kons
