The wikipedia article on bicubic interpolation appears to describe how to arrive at an equation for bicubic interpolation, but I cannot decipher it. Using the derivatives described I don't understand how to arrive at the relevant equation from the coordinates of the point and the values of the points around it.(adsbygoogle = window.adsbygoogle || []).push({});

I don't understand why I can't understand this.
