WebFeb 23, 2024 · My comment shows how inf can occur for non-infinite values even when examining data inside the region. However, probably what is happening for you is that you are asking for values at a location outside the maximum triangulation of the scattered data, and you have your interpolation configured to return inf in that case. http://thistechplanetz.com/2024/08/03/infinity-in-matlab/ endi trendy cateye
