Allows users to find a piecewise linear regression approximation to a given continuous univariate function within a specified error tolerance. Methods based on Warwicker and Rebennack (2025) "Efficient continuous piecewise linear regression for linearising univariate non-linear functions"
pwlapprox2d approximates continuous univariate functions using
adaptive piecewise linear regression. It produces a piecewise linear
approximation of a function over a specified domain until the desired
accuracy is reached.
