Matrix is Invertible: is this notation ok?

  1. Oct 2, 2015 #1
    Quick question, not even sure if I should post it here, but I can't think where else. If I wanted to write the short hand of A is an invertible matrix, would it be ok to just write

    [tex]A \ \exists A^{-1}[/tex]

    That looks strange to me. It's better to just say that A is invertible. Trying to use short hand will just be confusing.

    "[itex]\det(A) \neq 0[/itex]"

    I agree with FactChecker. Just say (in words) that A is invertible. Sometimes notation is not helpful in communicating clearly.
