Therefore,the formula of Jacobi iteration is simple;it only requires to calculate the multiplication of matrix and vector once at every iterations.During the calculation,the original matrix A keeps constant,ins
Scalar or vector step size factor for finite differences. When you setFiniteDifferenceStepSizeto a vectorv, the forward finite differencesdeltaare delta = v.*sign′(x).*max(abs(x),TypicalX); wheresign′(x) = sign(x)exceptsign′(0) = 1. Central finite differences are ...
It is well known that the Allen-Cahn equation satisfies the maximum bound principle and the energy dissipation law. Such two properties are important in the study of the stability of the solution to the Allen-Cahn equation, and whether they could be inherited at the discrete level is a signif...
The differences between the two results can be used to identify the locations of the errors and to quantify the magnitudes local errors in the discrete model. These local error measures can be used to evaluate the accuracy of the solutions. The analysis can be terminated if it is sufficiently...
In an FDTD simulation, the electromagnetic field is obtained from the previous time step over the entire computational domain, so that computation of relevant quantities such as electric and magnetic energy densities, Poynting vector, absorbed power, etc., at each time step is also possible. FDTD...

It makes use of a T-DNA vector containing the intact pea rbcS-3A gene as a reference gene. At 5 kb distance from the reference gene a pseudo wild-type rbcS-3A gene was inserted with a 3′ tail derived from the related rbcS-E9 gene. Transcript levels varied between plants but the two...

Operating under the assumptions of linear, isotropic materials, it utilizes a finite-difference method on a staggered grid to solve for the acoustic eigenmodes (field and frequency) of the vector-field elastic wave equation with a given propagation constant. Free, fixed, symmetry, and anti-...
