{"abstract":"In linear algebra, is the canonical forms of a linear transformation. Given a particularly nice basis for the vector spaces in which one is working, the matrix of a linear transformation may also be particularly nice, revealing some information about how the transformation operates on the vector space.The spectral theorem provides a sufficient criterion for the existence of a particular canonical form. Specifically, the spectral theorem states that if A equals the transpose of A, then A is diagonalizable: there exists an invertible matrix B such that B-1 AB is a diagonal matrix.","abstract_source":"original","authors":["Noriebelle Balbontin"],"date":"2022-10-04","doi":"10.5281/zenodo.7140908","id":641,"issue":7,"journal":{"issn":"2822-4353","name":"Psychology and Education: A Multidisciplinary Journal"},"pdf_sha256":"390599c0ab01937e010c62956eeb2fa6a576c846fa027a39235140c3148cedd3","schema":"scimatic-article/1","title":"Spectral Theorem: Diagonalizable Symmetric Matrix","volume":4}

Check it yourself

1. The record, from the token's own metadata:

printf '%s' "$(curl -s https://scimatic.org/nft/articles/641.json | jq -r .canonical_record)" | sha256sum

2. The hash stored on chain (contentHash(641)):

curl -s https://rpc.scimatic.net -H 'content-type: application/json' \
  -d '{"jsonrpc":"2.0","id":1,"method":"eth_call","params":[{"to":"0x0E596B4bb924937aA35D9b342A90347ed6F05eF8","data":"0xf3e0c2900000000000000000000000000000000000000000000000000000000000000281"},"latest"]}'

The two must be equal (the second with a 0x in front).
