From the chats it sounds like a lot of people used to use double transpose to turn a vector into an nx1 column vector. This helps users find the command which recovers that behavior.

Oh my bad. Fixed.

the "nx1-sized" part was fine, it was saying "To create a ... vector out of a vector" that I was commenting on
