- The signature for this method constructor is:
SparseVector(int size, int[] indices, double[] values)
The method inherits from the following which makes its concrete methods available to all routines:
interface class java.lang.Object
There are several method calls related to vectors that are of interest:
-
- Make a deep copy of the vector:
SparseVector Copy()
-
- Convert to the SparseVector. You will do this if your vector is long and the density decreases after a number of operations (for example, zero out non-contributing members):
DenseVector toDense()
-
- Find the number of non-zero elements. This is useful so you can convert on-the-fly to the SparseVector if the density ID is low.
Int numNonzeros()
-
- Convert ...
