WebSep 26, 2012 · Think of it this way: you could interpolate linearly by connecting consecutive data points with straight lines. You could fit any data this way and then describe the function in a mathematical form, but it would take a large number of parameters (at least as many as the number of points). WebIn mathematics, bilinear interpolation is a method for interpolating functions of two variables (e.g., x and y) using repeated linear interpolation. It is usually applied to functions sampled on a 2D rectilinear grid, though it can be generalized to functions defined on the vertices of (a mesh of) arbitrary convex quadrilaterals .
