<blockquote><p>This function adds the elements of vector <var>b</var> to the elements of
vector <var>a</var>, a'_i = a_i + b_i. The two vectors must have the
same length.
</p></blockquote></div>
<div class="defun">

<blockquote><p>This function subtracts the elements of vector <var>b</var> from the elements of
vector <var>a</var>, a'_i = a_i - b_i. The two vectors must have the
same length.
</p></blockquote></div>
<div class="defun">
— Function: int <b>gsl_vector_mul</b> (<var>gsl_vector * a, const gsl_vector * b</var>)<var><a name="index-gsl_005fvector_005fmul-893"></a></var><br>
<blockquote><p>This function multiplies the elements of vector <var>a</var> by the elements of
vector <var>b</var>, a'_i = a_i * b_i. The two vectors must have the
same length.
</p></blockquote></div>
<div class="defun">
— Function: int <b>gsl_vector_div</b> (<var>gsl_vector * a, const gsl_vector * b</var>)<var><a name="index-gsl_005fvector_005fdiv-894"></a></var><br>
<blockquote><p>This function divides the elements of vector <var>a</var> by the elements of
vector <var>b</var>, a'_i = a_i / b_i. The two vectors must have the
same length.
</p></blockquote></div>
<div class="defun">
— Function: int <b>gsl_vector_scale</b> (<var>gsl_vector * a, const double x</var>)<var><a name="index-gsl_005fvector_005fscale-895"></a></var><br>
<blockquote><p>This function multiplies the elements of vector <var>a</var> by the constant
factor <var>x</var>, a'_i = x a_i.
</p></blockquote></div>
<div class="defun">
— Function: int <b>gsl_vector_add_constant</b> (<var>gsl_vector * a, const double x</var>)<var><a name="index-gsl_005fvector_005fadd_005fconstant-896"></a></var><br>
<blockquote><p>This function adds the constant value <var>x</var> to the elements of the
vector <var>a</var>, a'_i = a_i + x.
