INVDISTGRID Simple, robust gridding using inverse-distance interpolation.

INVDISTGRID Simple, robust gridding using inverse-distance interpolation.
[Xi,Yi,Zi] = invdistgrid[X,Y,Z,dx] Grids values in vector Z with coordinates X and Y into an array with spacing dx using inverse-distance weighting (default power =2). All data between grid points are used in weighting. If no data exists between points, a NaN is entered. X and Y must be vectors and Z must be of the same length. Z can be an m by n array, with each column a dataset, and Zi will be a three-dimensional array with n layers.

[Xi,Yi,Zi] = invdistgrid[X,Y,Z,dx,p] Replaces the default weighting power 2 with the integer p. The higher the value of p, the more weight will be given to closer data values.

NOTE: You can use FILLNANS or INPAINT_NANS to fill in the NaN values in Zi.
