Hi, so in version 3 of ITensor we have replaced the type of an Index with a set of “Index tags” which are up to four short strings such as “Site” or “n=5” which can describe or label an Index.

The function closest to findtype in version 3 is findIndex, which is described near the bottom of the following documentation page:
http://itensor.org/docs.cgi?vers=cppv3&page=classes/itensor

Please post a comment below if you have more questions about this or Index tags in v3.

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.
