Bilineare Interpolation Beispiel
Using the rise over run formula for the slope of the line we solve.
Bilineare interpolation beispiel. Linear interpolation assumes that the unknown rate r. For example if w is the span of a vector v then w w if and only if v is isotropic. The first step is to implement simple linear interpolation between two points x0 y0 and x1 y1. Function v interp2d x y v x y calculate lower bound in x direction.
