Calls Lapacks Dsyev routine to compute eigenvalues and eigenvectors of a dense matrix.
This uses Ipopt's interface to Lapack.

SCIP_Real * | A, | ||
SCIP_Real * | b, | ||

solves a linear problem of the form Ax = b for a regular matrix A
Calls Lapacks DGETRF routine to calculate a LU factorization and uses this factorization to solve the linear problem Ax = b.
This uses Ipopt's interface to Lapack.
