n*V+V ( alpha x y -- alpha*x+y )
Basic Linear Algebra Subroutines (BLAS) interface » BLAS interface vector operations

Prev:	n*V+V! ( alpha x y -- y=alpha*x+y )
Next:	V+ ( x y -- x+y )

Vocabulary
math.blas.vectors

Inputs

alpha	a number
x	a blas-vector-base
y	a blas-vector-base

Outputs

alpha*x+y

a blas-vector-base

Word description
Calculate the vector sum αx + y and return a freshly-allocated vector with the same length as x and y containing the result. Corresponds to the xAXPY routines in BLAS.
