    load matrix into a vector of vectors

    hi,

    is there an efficient for to insert the elements of a 2d array into a vector of vectors?
    I have
    Code:
    	vector< vector <int> >  Points

	for (i = 0; i < n; i++ )
	  	Points.push_back(vector<int>(d));

        int Matrix[n][d];

        //populate matrix....

        //How to load the data in the Matrix into the vector of v.
    ...

      partition a vector of vectors

      hi,

      I am working in this problem, where I have a set of N d-dimensional points, e.g. (4,5,6,8) (2,0,4,6), are 4-d points, which I have stored in a vector of vectors.

      I am trying to partition the vector of vectors according to the median value of one the dimensions.

      I tried to use the stl partition method like this:

      // S is a vector of vectors containing the points
      vector < vector...

        help with sorting d-dimensional points

        Hi, I would like some help as how to approach the following problem:

        I have a set of d-dimensional points (e.g (3,5,8,9,5) is a 5-dimensional point), and I need to sort the points on each of the coordinates.
        The algorithm that I am trying to implement says that the resulting data structure is a multi-pointer list ((d-1)tuply threaded list), each node of which is threaded in each of the single pointer lists corresponding to the...
