formulas

Module containing the update formulas for the Vinv updates of the split^k-plot algorithm

Functions

compute_update_UD(level, grp, Xi_old, X, ...)	Compute the update to the information matrix after making a single coordinate adjustment.
det_update_UD(U, D, Minv)	Compute the determinant adjustment as a factor.
inv_update_UD(U, D, Minv, P)	Compute the update of the inverse of the information matrix.
inv_update_UD_no_P(U, D, Minv)	See inv_update_UD, but without precomputing the P-matrix.
