Member Function Documentation

Abstract::Vector & Vector::init (  double  value  )  [virtual]

Initialize every element of this vector with gamma. Here x represents this vector, and we update it as Returns: Reference to this object Implements NOX::Abstract::Vector.

int Vector::length (   )  const [virtual]

Return the length of vector. Returns: The length of this vector Note: Even if the vector is distributed across processors, this should return the global length of the vector. Implements NOX::Abstract::Vector.

Abstract::Vector & Vector::scale (  double  gammaval  )  [virtual]

Scale each element of this vector by gamma. Here x represents this vector, and we update it as Returns: Reference to this object Implements NOX::Abstract::Vector.
