inline

Compute the trace of an inverse quadratic form premultiplied by a square matrix.

This computes trace(D B^T A^-1 B) where D is a square matrix and the LDLT_factor of A is provided.

Template Parameters

Td	type of the first matrix
Ta	type of matrix in the LDLT_factor
Tb	type of the second matrix

Parameters
