Examples of cern.colt.matrix.DoubleMatrix3D.aggregate()

cern.colt.matrix.DoubleMatrix3D.aggregate()
x[slice,row,col]*x[slice,row,col] ) matrix.aggregate(F.plus,F.square); --> 140 For further examples, see the package doc. @param aggr an aggregation function taking as first argument the current aggregation and as second argument the transformed current cell value. @param f a function transforming the current cell value. @return the aggregated measure. @see cern.jet.math.Functions


DoubleMatrix3D x = cern.colt.matrix.DoubleFactory3D.dense.ascending(2,2,2);
System.out.println(x);


// Sum( x[slice,row,col]*x[slice,row,col] ) 
System.out.println(x.aggregate(F.plus,F.square));
//--> 140




DoubleMatrix3D y = x.copy();
// Sum( (x[i]+y[i])^2 )
