		const EigMat2 &	B
	)

inline

Return the quadratic form \( B^T A B \) of a symmetric matrix.

Symmetry of the resulting matrix is guaranteed.

Template Parameters

EigMat1	type of the first (symmetric) matrix
EigMat2	type of the second matrix

Parameters

A	symmetric matrix
B	second matrix

Exceptions

std::invalid_argument if A is not symmetric, or if A cannot be multiplied by B
