the book of learning opencv3 said that m0.push_back( s ) is used to extend an m × 1 matrix and insert the singleton s at the end while m0.push_back( m1 ) is used to extend an m × n by k rows and copy m1 into those rows; Cloud you tell me what's the different between s and m1 in the term of class?Does the singleton means the a single number?
i have no idea, what they mean with "singleton" there (it's probably just misleading),
but push_back() is quite easy to explain: you add 1 or more rows to the bottom of an existing matrix. like:
1 1 1
1 1 1
+
3 3 3
=
1 1 1
1 1 1
3 3 3
it does the same as vconcat(), btw.
the restriction here is, that your newly added line(s) must have the same number of cols as the original Mat (easy to see in the example above i hope!)
