CARDINAL SERIES INTERPOLATION TO NONUNIFORM GRIDS

[摘要] We consider Whittaker's cardinal series interpolation from a uniform grid to a nonuniform grid. It is shown that the interpolation is a bounded linear map if and only if a constraint on the clustering of the nonuniform grid is satisfied. An error estimate showing the spectral accuracy of the cardinal series interpolation is also presented. (C) 1994 Academic Press, Inc.
