Hi all,
I see we have
Sparse ITensors as
Single Element ITensor
Combiner
Delta and Diagonal ITensor
Also, IQTensor for block-sparse matrix.
However, is there any support for original sparse matrix which is defined as non-zero elements are less than half of total elements and doesn't have specific structure?
I was hoping to QR decompose a very large rectangle sparse matrix such as 4^30 x 4.
Thank you very much!
Best,
Victor

Hi Victor,

Unfortunately we don't have support for general sparse tensors beyond the ones that you listed (though that would be great to have). For now and in the foreseeable future you would have to look for another library for that.

Cheers,
Matt

Thank you so much!
I understand it might be beyond this website.
Do you recommend any library can go with MPI such as Eigen?

Formatting Tips:
  • To format code, indent by four spaces
  • To format inline LaTeX, surround it by @@ on both sides
  • To format LaTeX on its own line, surround it by $$ above and below
  • For LaTeX, it may be necessary to backslash-escape underscore characters to obtain proper formatting. So for example writing \sum\_i to represent a sum over i.
