``A systematic framework for high-order finite difference
compact schemes''
¡ã¸¦µæÈ¯É½Í×»Ý¡ä
We derive high-order compact schemes for the Poisson equation in one
and two dimensions. For 1D problems, the derivation is of arbitrary
even-order in theory and upt to 20th-order in 64-bit IEEE arithmetic.
For 2D problems, we derive up to tenth-order compact schemes.
