Functions | |
real function | slansy (norm, uplo, n, a, lda, work) |
SLANSY returns the value of the 1-norm, or the Frobenius norm, or the infinity norm, or the element of largest absolute value of a real symmetric matrix. | |
subroutine | slaqsy (uplo, n, a, lda, s, scond, amax, equed) |
SLAQSY scales a symmetric/Hermitian matrix, using scaling factors computed by spoequ. | |
subroutine | slasy2 (ltranl, ltranr, isgn, n1, n2, tl, ldtl, tr, ldtr, b, ldb, scale, x, ldx, xnorm, info) |
SLASY2 solves the Sylvester matrix equation where the matrices are of order 1 or 2. | |
subroutine | ssyswapr (uplo, n, a, lda, i1, i2) |
SSYSWAPR applies an elementary permutation on the rows and columns of a symmetric matrix. | |
subroutine | stgsy2 (trans, ijob, m, n, a, lda, b, ldb, c, ldc, d, ldd, e, lde, f, ldf, scale, rdsum, rdscal, iwork, pq, info) |
STGSY2 solves the generalized Sylvester equation (unblocked algorithm). | |
