Hi!
At
http://www.gnu.org/software/gsl/manual/html_node/Level-2-GSL-BLAS-Interface.html
a "Plus"-sign is missing:
— Function: int gsl_blas_cher2 (CBLAS_UPLO_t Uplo, const gsl_complex_float
alpha, const gsl_vector_complex_float * x, const gsl_vector_complex_float * y,
gsl_matrix_complex_float * A)
— Function: int gsl_blas_zher2 (CBLAS_UPLO_t Uplo, const gsl_complex alpha,
const gsl_vector_complex * x, const gsl_vector_complex * y, gsl_matrix_complex
* A
These functions compute the hermitian rank-2 update A = \alpha x y^H + \alpha^*
y x^H A of the hermitian matrix A. Since the matrix A is hermitian only its
upper half or lower half need to be stored. When Uplo is CblasUpper then the
upper triangle and diagonal of A are used, and when Uplo is CblasLower then the
lower triangle and diagonal of A are used. The imaginary elements of the
diagonal are automatically set to zero.
Between "rank-2 update A = \alpha x y^H + \alpha^* y x^H" and "A of the
hermitian matrix A" should be inserted a "+"-sign.
Kind regards!
