Dear Grass'ers, I am new to Grass and wondered if Grass provides a radial basis function method to interpolate / extrapolate 4D data. Basically, I need to get (interpolate / extrapolate) a velocity field in a three-dimensional volume given several sampling data in the space. If written in a function format, it looks like
result_new = f(x[], y[], z[], result[], xnew, ynew, znew); where, x[], y[], z[], and result[] are known. (xnew, ynew, znew) represent a point in space and result_new returns the result. Can someone please advice? If Grass cannot handle this, can someone please point other libraries to me that might be able to do so. Matlab's griddata3 only does linear interpolation that doesn't help. Thank you very much!
