?sysv function

Computes the solution to the system of linear equations with a real or complex symmetric coefficient matrix
A
and multiple right-hand sides.

Fortran-77 Interface

Calling from Fortran:
call ssysv(uplo, n, nrhs, a, lda, ipiv, b, ldb, work, lwork, info) call dsysv(uplo, n, nrhs, a, lda, ipiv, b, ldb, work, lwork, info) call csysv(uplo, n, nrhs, a, lda, ipiv, b, ldb, work, lwork, info) call zsysv(uplo, n, nrhs, a, lda, ipiv, b, ldb, work, lwork, info)
Calling from C:
ssysv(uplo, n, nrhs, a, lda, ipiv, b, ldb, work, lwork, info); dsysv(uplo, n, nrhs, a, lda, ipiv, b, ldb, work, lwork, info); csysv(uplo, n, nrhs, a, lda, ipiv, b, ldb, work, lwork, info); zsysv(uplo, n, nrhs, a, lda, ipiv, b, ldb, work, lwork, info);
