Input UPLO Specifies whether a triangular matrix is upper or lower
triangular. Use either BLAS_UPPER or BLAS_LOWER.
TRANS Specifies whether to apply the matrix (A), its transpose
(A
T
), or its conjugate transpose (A*). Use one of the
following:
BLAS_NO_TRANS
BLAS_TRANS
BLAS_CONJ_TRANS
DIAG Specifies whether the triangular matrix has
unit-diagonal or not. Use one of the following:
BLAS_UNIT_DIAG or BLAS_NON_UNIT_DIAG.
N Number of rows and columns in matrix A, and
elements of vector X. n > 0. If , the subprograms
do not reference A or X.
ALPHA The scalar ALPHA.
AP Array containing the upper or lower triangle, as
specified by uplo of an n-by-n real symmetric or
complex Hermitian matrix A, stored by columns in
packed form.
X REAL or COMPLEX array, minimum length
(N - 1) x |incx| + 1.
