Sentence examples for a compact difference from inspiring English sources

2, a compact difference scheme is given.

In this paper, we derive and analyse a compact difference scheme for a distributed-order time-fractional diffusion-wave equation.

Ren et al. [25] proposed a compact difference scheme for this problem where the convergence order (O tau^{2-alpha }+h^{4})) was O tau^{2-alpha

This equation is approximated by a multi-term fractional diffusion-wave equation, which is then solved by a compact difference scheme.

The patent is titled "Difference extraction between two versions of data-tables containing intra-references" and covers a method for generating a compact difference result between an old and a new program.

Based on this idea, Wang and Vong [19] proposed a second order accuracy formula to approximate the time-fractional derivative and a compact difference scheme was established for solving the modified anomalous fractional sub-diffusion equation.

To demonstrate the accuracy and applicability of the proposed method in the present paper, four numerical examples are carried out by the algorithms presented in the previous section with a comparison with a linearized compact difference scheme [39] in the one-dimensional case.

A linearized compact difference scheme is constructed.

In this paper, we further analyze a combined compact difference (CCD) scheme proposed recently [T.K. Sengupta, V. Lakshmanan, V.V.S.N.

A combined compact difference scheme is developed for non-periodic problems (called NCCD henceforth) that simultaneously evaluates first and second derivatives, improving an existing combined compact difference (CCD) scheme.

We present an EXFMG method combined with a fourth-order compact difference scheme, a bi-quartic Lagrange interpolation and a simple extrapolation technique, to solve the 2D convection diffusion equation.
