public interface BandedMatrix
extends SquareMatrix

This class defines an interface for matrices defined such as if all matrix elements vanish outside a diagonally bordered "band" of some range and size: ai,j=0 if ji+k2 for some k1, k2 > 0. The quantities k1,k2 are called the left and right halfbandwidth respectively. The bandwidth of the matrix is k1 + k2 + 1. A band matrix with k1 = k2 = 0 is a diagonal matrix; a band matrix with k1 = k2 = 1 is a tridiagonal matrix. If one puts k1 = 0, k2 = n-1, one obtains the definition of a lower triangular matrix, for k1 = n-1, k2 = 0 an upper triangular matrix.
