1. Please load the asymmetric tensor field from "ocean/data/ocean.vti". The (1,1), (1,2), (2,1) and (2,2) entries are respectively given by the arrays A, B, C, and D

2. Compute the eigenvector partition of the dataset.

3. Save the degenerate points as "ocean/results/{agent_mode}/ocean_points.vtk" in legacy VTK format. 
Include a point array called DegeneracyType which classifies each degenerate point. 
It should have a value of 0 for trisectors and 1 for wedges.

4. Save the partition information from the eigenvector partition as "ocean/results/{agent_mode}/ocean_eigenvector.vti" as VTK image data. 
It should have a point array called "Partition" that stores the region identifiers as follows:
0: W_{c,s}. 1: W_{r,s}. 2: W_{r,n}. 3: W_{c,n}

5. Compute the eigenvalue partition of the dataset.

6. Save the partition information from the eigenvalue partition as "ocean/results/{agent_mode}/ocean_eigenvalue.vti" as VTK image data. 
It should have a point array called "Partition" that stores the region identifiers as follows:
0: positive scaling. 1: counterclockwise rotation. 2: negative scaling. 3: clockwise rotation. 4: anisotropic stretching.
