Algebra homomorphism -> isomorphism

Under "Compatibility with Hadamard products" we have "Vectorization is an algebra homomorphism from the space ..." More specifically, isn't it an isomorphism, and if so should we say this instead? 128.243.253.102 ( talk) 15:24, 7 July 2010 (UTC) reply

Row-major vectorization

In section "Notes" the expression for row-major vectorization looks just as the one in section "Compatibility with Kronecker products". It seems to me that this might not be correct. — Preceding unsigned comment added by \gduld ( talkcontribs) 10:06, 27 April 2022 (UTC) reply
