DTRSV

 
Solve a system of equations; real triangular coefficient matrix.
 
Classes  :  D2a3 . Solution of systems of linear equations, including matrix
                 inverses, and LU and related factorizations (real
                 nonsymmetric triangular matrices)
 
Type     : C subroutine in NAGC library (F06 sublibrary).
Access   : Proprietary. Many implementations available.
Precision: Double.
Note     : This procedure may also be invoked using the name f06pjc.
 
Usage    : void dtrsv(MatrixTriangle uplo, MatrixTranspose trans,
           MatrixUnitTriangular diag, Integer n, const double a[], Integer

Implementation of DTRSV from NAGC on ITL

 
ITL:       Unix Workstation Network, National Institute of Standards and
           Technology (NIST), Gaithersburg, MD. Available to NIST staff.
 
Precision: Double.
Note     : This procedure may also be invoked using the name f06pjc.
 
Access available only to NIST staff on internal Unix systems. They may access this
package provided the /itl tree is cross-mounted.
