| FIC_reorder_univar | Univariate ordering under FIC approximation, first m chosen by m iter of dense univariate reordering |
| find_nn_corr | Find ordered nearest neighbors based on a correlation Matrix. Assuming the absolute value of the correlation is monotonically decreasing with distance. Returns an n X (m + 1) matrix similar to 'GpGp::find_ordered_nn'. |

| mvrandn | Simulate censored multivariate normal (MVN) as censored locations using the Vecchia approximation |
| pmvn | Compute multivariate normal (MVN) probabilities that have spatial covariance matrices using Vecchia approximation |
| ptmvrandn | Simulate censored multivariate normal (MVN) as censored locations using the Vecchia approximation |
| VeccTMVN | VeccTMVN |
| Vecc_reorder | Univariate ordering under Vecchia approximation |
