approxInvert {FuzzyNumbers}

Approximate the Inverse of a Given Function

Description

The function may be used to create side generating functions from alpha-cut generators and inversely.

Usage

approxInvert(f, method = c("monoH.FC", "linear", "hyman"), n = 500)

Arguments

f

a monotonic, continuous function f: [0,1]->[0,1]

method

interpolation method: “monoH.FC', “hyman” or “linear”

n

number of interpolation points

Details

The function is a wrapper to splinefun and approxfun. Thus, interpolation is used.

Value

Returns a new function, the approximate inverse of the input.
