Constructor & Destructor Documentation

ldltb()

subroutine pmat2::ldltb::ldltb	(	integer(spi), intent(in)	m,
		integer(spi), intent(in)	mah1,
		real(sp), dimension(m,-mah1:0), intent(inout)	a )

[L]*[D]*[L^T] factoring of symmetric band matrix A (root-free Cholesky).

[L] is lower triangular with unit main diagonal [D] is a diagonal matrix.

Parameters

[in]	m	size of symmetric matrix A
[in]	mah1	semi-bandwidth of matrix A
[in,out]	a	input lower (left) part of symmetric A; output its factors encoded as [L-I]+[D**-1]
