Abstract
In LAPACK we have two types of subroutines for solving problems with symmetric matrices: with full and packed storage. The performance of the full storage scheme is much better because it allows the usage of BLAS Level 2 and 3, while the memory requirements for the packed scheme are about twice less. Recently a new storage scheme was proposed which combines the advantages of both schemes: it has a performance similar to that of full storage, and the memory requirements are a little bit higher than for packed storage. In this paper we apply the scheme for inversion of symmetric indefinite matrices.
