N2 - Abstract: Continuous piecewise affine functions are widely used in computational mathematics. In the one-dimensional case, such functions are called broken lines. The paper analyzes the analytical representations of broken lines both in the forms accepted in the theory of polynomial splines and in the form of the difference of the maxima of two finite families of affine functions. We establish a correlation between these representations.
