Colt library is pretending to provide "Dense and sparse fixed sized (non-resizable) 1,2, 3 and d-dimensional matrices" (Section Features / Templated Multidimensional matrices).

But in API itself I see no any implementation, higher than 3: http://acs.lbl.gov/ACSSoftware/colt/api/cern/colt/matrix/package-summary.html

Please cure my tired eyes :)

  • What is "d"? n-dimensional? Couldn't you just consolidate multiple matrices into a custom class? – Mr. Polywhirl Jun 27 '14 at 10:40
  • Colt does obviously not support it, and I'm not aware of any library that can do this. (In fact: Even 3D is already rather unusual). Do you really need this as a *Matrix* including multiplication and other operations, or do you just need an "n-dimensional array"? (BTW: The Colt 3D matrices don't support many operations either...) – Marco13 Jun 27 '14 at 10:53
  • The question is just about matching between claims and reality. Actually I need tensors. – Suzan Cioc Jun 27 '14 at 11:59
