The griddata function interpolates the surface at the query points specified by (xq,yq) and returns the interpolated values, vq. In MATLAB, the row dimension is the first dimension, and the the column dimension is the second dimension. As to the difference between griddata and scatteredInterpolant the main difference as I understand it is that the latter gives you a function that you can effectively call multiple times and re-use the triangulation that both methods use to interpolate, while repeated. I am really confused by the function names *griddata* and *griddatan*, because these function names are prefixed by *grid* whereas the functions are actually doing *scattered* data interpolation, r. The griddatan function interpolates the surface at the query points specified by xq and returns the interpolated values, vq.
