Examples of cc.mallet.types.SparseMatrixn

cc.mallet.types.SparseMatrixn
Implementation of Matrix that allows arbitrary number of dimensions. This implementation simply uses a flat array. Created: Tue Sep 16 14:52:37 2003 @author Charles Sutton @version $Id: SparseMatrixn.java,v 1.1 2007/10/22 21:37:39 mccallum Exp $


    int[] idxs1 = new int[] { 0, 1, 3 };
    double[] vals1 = new double[]{ 2.0, 4.0, 8.0 };


    TableFactor ptl1 = new TableFactor (vars);
    ptl1.setValues (new SparseMatrixn (szs, idxs1, vals1));


    TableFactor ans = new TableFactor (vars[0], new double[] { 6, 8 });


    Factor ptl2 = ptl1.marginalize (vars[0]);
