Interpolate NaN elements in a 2-d array using non-NaN elements. Can also extrapolate, as it does not use a triangulation of the data. Inpaint_nans offers several different approaches to the interpolation, which give tradeoffs in accuracy versus speed and memory required. All the methods current...

The LM algorithm [6] interpolates between gradient descent and Gauss-Newton methods, and can be more robust for small neural networks. It approximates second order derivatives using a Jacobian outer product. Use the LM algorithm for regression networks with small numbers of learnable parameters, wh...
I used the 'normalize' function for a set of data and then I used fitsurface to interpolate them with e surface in space. This is the code: A = [4.6; 9.3; 13.9; 18.6; 23.5; 28.5]; X = normalize(A,'range'); B = [10; 20; 30; 40; 50; 60]; ...
