Component type:function

Prototype

template <class VecW, class VecX, class VecY, class VecZ> void add(const VecX& x, const VecY& y, const VecZ& z, VecW w) ;

Description

Add the elements of x, y, and z and assign into w. For now just dense vectors.

Definition

mtl.h

Requirements on types

VecX::value_type, VecY::value_type, VecZ::value_type, and VecW::value_type should be the same type
The addition operator must be defined for the value_type.

Preconditions

Complexity

linear time

Example

In vecvec_add3.cc:

  dense1D<double> x(20,2), y(20,3), z(10,1), w(10);
  add(strided(x,2), strided(y,2), z, w);
