I'm trying out the qr function in Octave version 4.0.  According to the user
guide page 474, the following is a valid usage: [C, R]=qr(A,B,'0'), but I
get an error when trying it:

printf("Octave version = %s\n",version);
A = [1, 2; 3, 4]
B = [0.2; 4]
[C, R] = qr (A, B, '0')

error: Invalid call to qr.  Correct usage is:

 -- Loadable Function: [Q, R, P] = qr (A)
 -- Loadable Function: [Q, R, P] = qr (A, '0')
 -- Loadable Function: [C, R] = qr (A, B)
 -- Loadable Function: [C, R] = qr (A, B, '0')

Oddly, the error message says that valid usage is exactly what I tried.
What's going on?

I see the same thing you are seeing, and I don't know why it is not working.
