C++ (Cpp) VectorXf::data Examples

Example #1

File: cloud_math.cpp Project: cutun/kazoo

double density (const VectorXf & x)
{
  const size_t I = x.size();

  double sum_x1 = 0;
  double sum_x2 = 0;

  const float * restrict x_ = x.data();

  for (size_t i = 0; i < I; ++i) {
    double xi = x_[i];

    sum_x1 += max(-xi,xi);
    sum_x2 += xi * xi;
  }

  return sqr(sum_x1) / sum_x2 / I;
}

Example #2

File: eigen.cpp Project: cutun/kazoo

Vector<float> as_vector (const VectorXf & x)
{
  return Vector<float>(x.size(), const_cast<float *>(x.data()));
}
