Detailed Description

template<typename T, class idx_t = std::size_t>
struct tlapack::LegacyBandedMatrix< T, idx_t >

Legacy banded matrix.

Mind that the access A(i,j) is valid if, and only if, max(0,j-ku) <= i <= min(m,j+kl) This class does not perform such a check, otherwise it would lack in performance.

Template Parameters

T	Floating-point type
idx_t	Index type

Access A(i,j) = ptr[ (ku+(i-j)) + j*(ku+kl+1) ].

Mind that this access is valid if, and only if, max(0,j-ku) <= i <= min(m,j+kl) This operator does not perform such a check, otherwise it would lack in performance.
