OpenCV SVD Matrix format.
- by Rick
I currently have a set of 2D Cartesian coordinates e.g. {(1,3), (2,2), (3,4)}
Which will be put into a 2D array, to perform SVD properly would the matrix be put together such that the coordinates form the columns or the rows e.g.
1 3
2 2
3 4
or
1 2 3
3 2 4
I have been doing a little trial and error comparing to examples of SVD I have found online, the resulting matrix usually seems to be negated, with some of the values shuffled around.
To clarify further if I had a matrix E which was MxN as shown here http://upload.wikimedia.org/wikipedia/commons/b/bb/Matrix.svg
To define the matrix as a 2D array would it be Array[M][N] or Array[N][M]
I am assuming this actually matters due to matrix arithmetic not being commutative? Can anyone actually verify this?
