Coarse function

In mathematics, coarse functions are functions that may appear to be continuous at a distance, but in reality are not necessarily continuous.^[1] Although continuous functions are usually observed on a small scale, coarse functions are usually observed on a large scale.^[1]

To evaluate a coarse function at a certain point, a set of nonlinear system of equations must be solved, making the computational cost of solving a coarse system fairly high.^[2]
