output_index_1D()

unsigned int RBThetaExpansion::output_index_1D ( unsigned int  n, unsigned int  q_l  ) const

inherited

Computes the one-dimensional index for output n, term q_l implied by a "row-major" ordering of the outputs.

This is useful for indexing into pre-evaluated theta arrays, which store the pre-evaluated output theta values in this order following the "A" and "F" theta values.

  // Start with index of the current term
  unsigned int index = q_l;
 
  // Add to it the number of terms for all outputs prior to n
  for (auto i : make_range(n))
    index += _output_theta_vector[i].size();
