I am attempting to interpolate across a 6-dimensional, non-monotonic, real domain. I'm using MATLAB. I am pretty sure that the function "griddatan" will do, but when I try to run it, I get the following error from one of its subroutines: "Error using qhullmx The data is degenerate in at least one dimension - ND set of points lying in (N+1)D space."
However, all of my input matrices comply with the documentation and are not dimensionally-degenerate.
Anyone ever had this problem? I'm sorry I can't provide much more context. If you know of any other way to interpolate ungridded 6D data, please let me know!
Thanks, Kevin
