List of viewRow() Examples

Examples of viewRow()

cern.colt.matrix.DoubleMatrix2D.viewRow()
Constructs and returns a new slice view representing the columns of the given row. The returned view is backed by this matrix, so changes in the returned view are reflected in this matrix, and vice-versa. To obtain a slice view on subranges, construct a sub-ranging view (viewPart(...)), then apply this method to the sub-range view.
Example:

2 x 3 matrix:
1, 2, 3
4, 5, 6 viewRow(0) ==> Matrix1D of size 3:
1, 2, 3

@param row the row to fix. @return a new slice view. @throws IndexOutOfBoundsException if row < 0 || row>= rows(). @see #viewColumn(int)
cern.colt.matrix.ObjectMatrix2D.viewRow()
Constructs and returns a new slice view representing the columns of the given row. The returned view is backed by this matrix, so changes in the returned view are reflected in this matrix, and vice-versa. To obtain a slice view on subranges, construct a sub-ranging view (viewPart(...)), then apply this method to the sub-range view.
Example:

2 x 3 matrix:
1, 2, 3
4, 5, 6 viewRow(0) ==> Matrix1D of size 3:
1, 2, 3

@param row the row to fix. @return a new slice view. @throws IndexOutOfBoundsException if row < 0 || row>= rows(). @see #viewColumn(int)
org.apache.mahout.math.DenseMatrix.viewRow()
org.apache.mahout.math.Matrix.viewRow()
org.apache.mahout.math.SparseRowMatrix.viewRow()
@param row an int row index @return a shallow view of the Vector at specified row (ie you may mutate the original matrix using this row)
org.apache.mahout.math.matrix.DoubleMatrix2D.viewRow()
Constructs and returns a new slice view representing the columns of the given row. The returned view is backed by this matrix, so changes in the returned view are reflected in this matrix, and vice-versa. To obtain a slice view on subranges, construct a sub-ranging view (viewPart(...)), then apply this method to the sub-range view.

@param row the row to fix. @return a new slice view. @throws IndexOutOfBoundsException if row < 0 || row>= rows(). @see #viewColumn(int)
stallone.api.doubles.IDoubleArray.viewRow()
Gets an IDoubleArray object which is a view on row i @param i @return

Examples of org.apache.mahout.math.matrix.DoubleMatrix2D.viewRow()

    //int nx = B.columns();


    // precompute and cache some views to avoid regenerating them time and again
    DoubleMatrix1D[] Xrows = new DoubleMatrix1D[n];
    for (int k = 0; k < n; k++) {
      Xrows[k] = X.viewRow(k);
    }


    // Solve L*Y = B;
    for (int k = 0; k < n; k++) {
      for (int i = k + 1; i < n; i++) {

Examples of stallone.api.doubles.IDoubleArray.viewRow()

        {
            // scale diagonal
            Tnew.set(i,i, Math.pow(Tnew.get(i,i), 1.0/timescaleFactor));
            
            // compute off-diagonal scaling factor
            double cOffdiag = (1.0 - Tnew.get(i,i)) / (alg.sum(Tnew.viewRow(i)) - Tnew.get(i,i));
            
            for (int j=0; j<Tnew.columns(); j++)
