ifsgfif

Generates Generates a Generalized Fractal Interpolation function with prescribed Holder function based on Iterated Function System

Syntax

IFS = ifsgfif(N,MI,H)

Description

IFS = ifsgfif(N,MI,H) Generates the generalized fractal interpolation function, IFS, using a sample size, N, 3 interpolation points, arranged as a 3x2 matrix, MI, and Holder function, H. This allows to model a process the pointwise regularity of which varies in time. The parameter N is a positive, power of 2, integer and the parameter MI is real and the parameter H must be a function from R to (0,1), written in a symbolic way.
