Member Function Documentation

void Vec2D::operator= (  const Vec2D &  vec2D  )

assignment e.g. vec1 = vec2;

double Vec2D::operator * (  const Vec2D &  vec2D  )  const

arithmetic scalar product, e.g. val = vec1 * vec2;

const Vec2D& Vec2D::operator * (  double  val  )  const

arithmetic vector multiplication, e.g. vec1 = val * vec2 (also working: vec1 = vec2 * val; )

const Vec2D& Vec2D::operator+ (  const Vec2D &  vec2D  )  const

arithmetic addition, e.g. vec1 = vec2 + vec3;

const Vec2D& Vec2D::operator- (  const Vec2D &  vec2D  )  const

arithmetic subtraction, e.g. vec1 = vec2 - vec3;
