8.3.6 Copying vectors
Common operations on vectors such as addition and multiplication are
available in the blas part of the library (see BLAS Support). However, it is useful to have a small number of utility
functions which do not require the full blas code. The following
functions fall into this category.
— Function: int
gsl_vector_memcpy (
gsl_vector * dest, const gsl_vector * src)
This function copies the elements of the vector src into the
vector dest. The two vectors must have the same length.
— Function: int
gsl_vector_swap (
gsl_vector * v, gsl_vector * w)
This function exchanges the elements of the vectors v and w
by copying. The two vectors must have the same length.
