The command minors(b,3) returns a matrix with one row whose entries are the 3x3 minors of b (when, of course, b is a matrix with at least 3 rows and at least 3 columns). The entries of the output matrix are arranged in ascending order, and repeats are eliminated. Thus, minors(eye(4),3) returns the 1x2 matrix whose entries are 0, 1, in that order.
