Kernel matrices embrace a rich structure that enables more efficient storage and computation than does a usual n-by-n dense matrix.We present an O(n)data structure for compressing a kernel matrix and O(n)algorithms for various matrix operations,including matrix-vector multiplication,matrix inversion,determinant,and square root calculation.
