nonAdaptive

TypeScript

static get nonAdaptive(): Quadrature_Integrator

Swift declaration

static let nonAdaptive: Quadrature.Integrator

Simple non-adaptive automatic integrator using Gauss-Kronrod-Patterson quadrature coefficients. Evaluates 21, or 43, or 87 points in the interval until the requested accuracy is reached.

adaptiveWithSingularities

TypeScript

static adaptiveWithSingularities(maxIntervals: number): Quadrature_Integrator

Swift declaration

static func adaptiveWithSingularities(maxIntervals: Int) -> Quadrature.Integrator

Global adaptive quadrature based on 21-point or 15-point (if at least one bound is infinite) Gauss–Kronrod quadrature within each subinterval, with acceleration by Peter Wynn's epsilon algorithm. If at least one of the interval bounds is infinite, this is equivalent to the QUADPACK QAGI routine. Otherwise, this is equivalent to the QUADPACK QAGS routine.

adaptive

TypeScript

static adaptive(pointsPerInterval: Quadrature_QAGPointsPerInterval, maxIntervals: number): Quadrature_Integrator

Swift declaration

static func adaptive(pointsPerInterval: Quadrature.QAGPointsPerInterval, maxIntervals: Int) -> Quadrature.Integrator

Simple globally adaptive integrator. Allows selection of the number of Gauss-Kronrod points used in each subinterval, and the max number of subintervals.
