| Abstract: | Block methods for the finite difference Solution of one dimensional linear diffus- ion-convection equation are considered.No special starting porcedure is required for their implementation.All of the block methods derived in this paper are unco- nditionally stable or L-stable(L_0-stable)and have higher accuracy. |
