(SPPTRS/DPPTRS) solves a real symmetric positive-definite system of linear equations with multiple right-hand sides, A*X = B, where A has been factorized by F07GDF (SPPTRF/DPPTRF), using packed storage. Classes : D2b1b . Solution of systems of linear equations, including matrix inverses, and LU and related factorizations (real symmetric positive definite matrices) Type : Fortran subroutine in NAG library (F07 sublibrary). Access : Proprietary. Many implementations available. Precision: Double. Usage : CALL F07GEF(UPLO, N, NRHS, AP, B, LDB, INFO) See also : F07GDF Details : Documentation Example Example-input Example-output Sites : (1) AIX (2) ITL
