GSL function to replace catlas_daxpby

I want to replace catlas_daxpby function from ATLAS lib开发者_开发知识库rary with a GSL equivalent function. Is there any?

There's the Level 1 GSL BLAS Interface which indicates that there's a function:

int gsl_blas_daxpy (double alpha, const gsl_vector * x, gsl_vector * y)

There are also these vector operations that might have what you're looking for.
