3d interpolation
HI all- I have a three-D array 120*100*100, I wish to interpolate the data along the third dimension so that the end result is a matrix 120*100*199. The third dimension is equally spaced. The ouput array would have interpolated values at points between each of the rows and columns and the original data should not be... 18 Jun 2010 17:58
