Hi,

I have a data tensor of 12 dimensions, with the following distribution: (13,18,3,3,3,3,3,3,5,3,5,5).

I need to do the HOSVD of that tensor in order to keep only the most relevant information contained on it, allowing me to complete a bit faster the calculations I have to do (supposedly with some less accuracy, but not dramatically less) and de-noising the infomation. I'm expecting some dimension-reduction.

I can not see any HOSVD function or similar toolbox in my version of MATLAB.

I need to know if I need to get any additional app for such task and where do I find it. Also where can I find the documentation associated to such toolbox/function/etc and if there is any document with examples similar to the one I mentioned above?

Best regards and thanks for your support.

JRR
