### 8.3.6 Copying vectors

Common operations on vectors such as addition and multiplication are available in the blas part of the library (see 12). 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.
