LAPACK [cse]



LAPACK is written in Fortran 77 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.


Use of the LAPACK libraries is beyond the scope of this page. For information on how to utilize LAPACK, please consult the particular user guide of the system you are running on ( AFRL DSRC Documentation) or the LAPACK User Guide.
