In the website http://www.math.cornell.edu/~mec/Winter2009/RalucaRemus/Lecture2/lecture2.html, the author says that the matrix
B=
1 1 0 0
0 1 0 0
1 1 1 1
2 1 0 1
is not positive, yet in http://en.wikipedia.org/wiki/Nonnegative_matrix I read
"A positive matrix is a matrix in which all the elements are greater than zero."
Discrepancy. What is going on?
Thanks.
