A vector is a vector is a vector

    Can anybody explain what does 'a vector is a vector is a vector' mean?

    It's a confusingly worded tautology. For a more helpful answer, a little more context is necessary.

    It's a reference to "a rose is a rose is a rose" from Gertrude Stein's Sacred Emily. It doesn't mean anything other than the author is making a little literary joke.

    Actually, the correct quote is "Rose is a rose is a rose" which has quite a different meaning.

    According to wikipedia:
    The sentence "Rose is a rose is a rose is a rose." was written by Gertrude Stein as part of the 1913 poem Sacred Emily, which appeared in the 1922 book Geography and Plays. In that poem, the first "Rose" is the name of a woman. Stein later used variations on the phrase in other writings, and "A rose is a rose is a rose" is probably her most famous quote, often interpreted as "things are what they are".​

    See hurkly's post. I'm perfectly aware of what Stein wrote and what people ascribe to her. It is one of the most famous misquotations there is.

    it's not even true, a column vector is not a row vector

    Now, perhaps you're being facetious, but who mentioned the words row or column?
