Type Declaration

• difference: (x0: number, x1: number) => number | null

• differences: (x0: number[], x1: number[]) => (number | null)[]

• erf: (x: number) => number

  Error function approximation of Abramowitz and Stegun, formula 7.1.26 in the Handbook of Mathematical Functions with Formulas, Graphs, and Mathematical Tables. Although the approximation is only valid for x ≥ 0, because erf(x) is an odd function, erf(x) = −erf(−x) and negative values are supported.

• interpolate: (xySequence: XySequence, value: number, mode?: InterpolateMode) => number

  Interpolate.

  Default

  InterpolateMode.LOG_LOG

• minMax: (data: number[]) => number[]

• normalCcdf: (μ: number, σ: number, x: number) => number

  Normal complementary cumulative distribution function.

• percentDifference: (x0: number, x1: number) => number

• percentDifferences: (x0: number[], x1: number[]) => number[]

• responseSpectrum: (hazards: Map<Imt, XySequence>, returnPeriod: number) => XySequence

  Calculate the response sepectrum for each IMT.

• round: (value: number, scale: number) => number

  Round a number to specific format
