This paper proposes a method to find multiresolution piecewise-linear (PWL) approximations of multivariate continuous nonlinear functions defined over limited compact domains. The method is derived from the context of PWL prewavelets on arbitrary triangulations and is aimed to the circuit implementations of the obtained approximations. Two illustrative examples are proposed in low-dimensional case studies.

Abstract
This paper proposes a method to find multiresolution piecewise-linear (PWL) approximations of multivariate continuous nonlinear functions defined over limited compact domains. The method is derived from the context of PWL prewavelets on arbitrary triangulations and is aimed to the circuit implementations of the obtained approximations. Two illustrative examples are proposed in low-dimensional case studies.
