SPBTRS

 
Solves a real symmetric positive definite banded system of linear equations
AX=B, using the Cholesky factorization computed by SPBTRF. (Computational
routine.).
 
Classes  :  D2b2 . Solution of systems of linear equations, including matrix
                 inverses, and LU and related factorizations (real symmetric
                 positive definite banded matrices)
 
Type     : Fortran subroutine in LAPACK package.
Access   : Public domain. Portable.
Precision: Single.
 
Usage    : CALL SPBTRS( UPLO, N, KD, NRHS, AB, LDAB, B, LDB, INFO )
