An alternative form of the fractal interpolation function (FIF)-previo
usly unmentioned in the signal processing literature-is noted. This fo
rm highlights a simple relationship between fractal and linear interpo
lation. Using this relationship, many FIF problems can be reduced to a
matrix/vector expression. This expression provides a more powerful wa
y to employ the FIF for interpolation and permits its adaptation for r
econstruction. Additionally, the alternate form of the FIF allows the
construction of fractal functions whose piecewise integrals match obse
rved data.
