Frames and numerical approximation
Functions of one or more variables are usually approximated with a basis; a complete, linearly independent set of functions that spans an appropriate function space. The topic of this paper is the numerical approximation of functions using the more general notion of frames; that is, complete systems that are generally redundant but provide stable infinite representations. While frames are well-...
متن کاملNumerical Analysis: Approximation of Functions
Task: A polynomial can be factorized to the product of linear polynomials, but only for orders up to 4. Numerical solution is possible, but it is imprecise and division leaves a remainder. Also this is a subject of numerical anaysis. Task: Linear algebra: “A system of linear equations Ax = b has a unique solution x = A−1b if and only if det A 6= 0.” Programming: “Real numbers cannot be tested f...
متن کاملStatistical mechanics of kinks in 1+1 dimensions: Numerical simulations and double-Gaussian approximation.
We investigate the thermal equilibrium properties of kinks in a classical Φ4 field theory in 1+1 dimensions. From large scale Langevin simulations we identify the temperature below which a dilute gas description of kinks is valid. The standard dilute gas/WKB description is shown to be remarkably accurate below this temperature. At higher, “intermediate” temperatures, where kinks still exist, th...
متن کامل8.2 Flash Memories & Numerical Approximation
In recent years, flash memory has been widely used in embedded systems, portable devices, and high-performance storage products due to its non-volatility, shock resistance, low power consumption, and high performance natures. To reduce the product cost, multi-level-cell flash memory (MLC) has been proposed; compared with the traditional single-level-cell flash memory (SLC) that only stores one ...
متن کاملNumerical approximation for integral equations
A numerical algorithm, based on a decomposition technique, is presented for solving a class of nonlinear integral equations. The scheme is shown to be highly accurate, and only few terms are required to obtain accurate computable solutions. 1. Introduction. Adomian polynomial algorithm has been extensively used to solve linear and nonlinear problems arising in many interesting applications (see...
