Then, we describe a numerical method to compute the dual function and give an estimate of the error.
In this paper, we prove the convergence of the nodal expansion method, a new numerical method for partial differential equations and provide the error estimates of approximation solution.
A uniform numerical method for quasilinear singular perturbation problem with a turning point
In this paper, a new numerical method, the coupling method of spherical harmonic function spectral and finite elements, for a unsteady transport equation is discussed, and the error analysis of this scheme is proved.
Moreover, the new model was solved through a numerical method and was illustrated with typical values of some ecological factors; three groups of curves were acquired by calculation with the VisualBasic program.
The mathematical theory usually addresses this problem in infinite dimensions (typically in L2 (?) or ?2(?)), whereas numerical methods have to operate with a finite-dimensional model.
Because of this perspective, several numerical methods become available to compute the tight frames.
Many numerical methods have been given by different authors to this system, but these methods need very high regularity conditions.
It further contains a summary of the basic concepts about microstructures and equilibrium properties, and of analytical and numerical methods, which are relevant for the theoretical description of the suspensions.
