# ppapp/R - piecewise polynomial approximation of real functions

Code generator for piecewise Chebyshev approximation of smooth real-valued functions.

## Overview

This package generates C source code containing polynomial coefficients that approximate
a given function f(x) over a specified domain. The approximation uses piecewise Chebyshev
polynomials with octave-based domain subdivision for optimal accuracy.
