The griddata and griddatan functions take a set of sample points, X, corresponding values, V, and query points, Xq, and return the interpolated values, Vq. Function File: yi = griddatan (x, y, xi) Function File: yi = griddatan (x, y, xi, method) Function File: yi = griddatan (x, y, xi, method, options) Generate a regular mesh from irregular data using interpolation.
