x1 = uniqrows(X)
Then, the matrix given is:
x1 = (
But what I need is:
x2 = (
Of course, this can be done easily for just this matrix, but the problem is that
I need the correct matrix as part of an estimation command (thus, the matrices
can be different everytime, dependent on the dataset at hand), so I need a sort
of general way to ensure the matrix is always sorted correctly. However, I've
not find a working strategy yet.
Kind regards, Alex
