Web“Interpolation”, in the DSP sense, is the process of upsampling followed by filtering. (The filtering removes the undesired spectral images.) ... The coefficients are h0-h11, and three data samples, x0-x2 (with the newest, x2, on the left) have made their way into the filter’s delay line: h0 h1 h2 h3 h4 h5 h6 h7 h8 h9 h10 h11 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.
