WebFeb 1, 2024 · One can also fit a thin plate spline to the same data by: p=1; st=tpaps ( [xData',yData'],zData',p) The resulting structure, st, includes st.coefs, which is a vector of 12 coefficients. By setting p=1, tpaps () returns an exact-fitting thin plate spline. As p decreases toward 0, the fit becomes increasingly approximate.
