	Numerical analysis - Wikipedia, the free encyclopedia
		Numerical analysis is the study of algorithms for the problems of continuous mathematics (as distinguished from discrete mathematics).
		The field of numerical analysis is divided in different disciplines according to the problem that is to be solved.
		Numerical analysis is also concerned with computing (in an approximate way) the solution of differential equations, both ordinary differential equations and partial differential equations.

	Numerical analysis Info - Encyclopedia WikiWhat.com
		Numerical analysis is that branch of applied mathematics which studies the methods and algorithms to find (approximate) numerical solutions to various mathematical problems, using a finite sequence of arithmetic and logical operations.
		Accuracy - the numerical approximation should be as accurate as possible and the error should be possible to estimate according to some scale.
		Numerical Analysis is also concerned with computing (in an approximate way) the solution of Partial Differential Equations.

	Numerical Analysis of Applied Partial Differential Equations
		Numerical analysis is the mathematical method that uses numerical approximations to obtain numerical answers to the problem.
		Numerical analysis also considers the accuracy of an approximation, and when the approximation is good enough.
		Numerical methods are needed most in situations with variable coefficients, inhomogeneities, or time dependent boundary conditions.

	Numerical Analysis
		The ability of a numerical method to control the effect of approximation errors is often one of the most crucial factors in determining which method to use.
		The problems involved with such an innocuous task are useful to motivate the study of numerical analysis.
		In the next numerical analysis lectures we will consider the problems involved in more advanced numerical methods, such as the solution of ordinary and partial differential equations, finding eigenvalues, and optimization methods (such as genetic algorithms).

	Numerical Analysis Technical Reports
		Numerical methods for both ordinary differential equations (ODEs) and delay differential equations (DDEs) are traditionally developed and assessed on the basis of how well the accuracy of the approximate solution is related to the specified error tolerance on an adaptively-chosen, discrete mesh.
		This may not be appropriate in numerical investigations that require visualization of an approximate solution on a continuous interval of interest (rather than at a small set of discrete points) or in investigations that require the determination of the `average' values or the `extreme' values of some solution components.
		Numerical results demonstrate that the QSC methods are optimal, that is, fourth order locally at certain points and third order globally, even for some problems that do not satisfy the conditions of the analysis.

		The area of numerical analysis is often called numerical computation, numerical methods, numerical mathematics, computational mathematics, scientific computing or mathematical software, depending which aspect of this broad subject that is being emphasized.
		One can argue that the reason computers were invented was to perform numerical computations, and scientific computing continues to be one of the main driving forces in the development of advanced computing architectures.
		Although we emphasize the numerical solution of differential equations, we are also active in several other areas, including special functions, polynomial root finders, linear algebra, optimization and language facilities for numerical computation.

	Numerical Analysis
		A point that is probably a surprise for many numerical analysts (and it was a surprise for me, too) is that not just formal integrability but indeed involution is of importance here.
		I show that obstructions to involution may turn into integrability conditions upon semi-discretisation so that even if the original system is formally integrable but not involutive, the DAE obtained by the semi-discretisation has hidden integrability conditions.
		In I have studied the numerical properties of the Hamilton-Dirac equations, the equations of motion derived with the Dirac bracket.
