LAPACK is written in Fortran 90 and provides routines for solving systems of
simultaneous linear equations, least-squares solutions of linear systems of
equations, eigenvalue problems, and singular value problems. The associated
matrix factorizations (LU, Cholesky, QR, SVD, Schur, generalized Schur) are
also provided, as are related computations such as reordering of the Schur
factorizations and estimating condition numbers. Dense and banded matrices
are handled, but not general sparse matrices. In all areas, similar
functionality is provided for real and complex matrices, in both single and
double precision. |
