SA-W on 20 Jun Yes the equation is derived by zeroing the cubic term, it is written in the paper. I am trying to interpolate a large array of points onto a regular grid.

I have also showed later the tensorial form in 2D here. Ah, such nostalgia. If a point x,y outside the grid domain is far apart, each kind of extrapolation tends to give unphysical results. Otherwise prived some data. Yes the equation is derived by zeroing the cubic term, it is written in the paper. I haven't thought of GriddedInterpolant it could help me to expand the array to more than 1 point. I do not understand what I am doing as the input fields obviously match in size because they are from the same array. I want to use interp2 to bi linearly interpolate the function Z x,y in the interior of the grid. You may receive emails, depending on your communication preferences. Requires at least two grid points in each dimension. Matrices X and Y specify the points at which the data Z is given. Skip to content.
