SyntaxThe DoubleSparseVector type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | DoubleSparseVector(Int32) |
Constructs a DoubleSparseVector instance sized for the given number
of non-zero entries. The resulting instance will not be useable until
the C# Entries C# Indices |
| DoubleSparseVector(Double, IndexArray) | Constructs a DoubleSparseVector instance from the given data. |
| DoubleSparseVector(DoubleVector, IndexArray) | Constructs a DoubleSparseVector instance from the given data. |
| DoubleSparseVector(Double, IndexArray, Int32) | Constructs a DoubleSparseVector instance from the given data. |
| DoubleSparseVector(DoubleVector, IndexArray, Int32) | Constructs a DoubleSparseVector instance from the given data. |
| DoubleSparseVector(Double, IndexArray, Int32, Boolean) | Constructs a DoubleSparseVector instance from the given data. |
Properties| Name | Description | |

Methods| Name | Description | |
|---|---|---|
 | Add(DoubleSparseVector, DoubleVector) | Adds a dense vector to a sparse vector. The result is a dense vector. |
| Add(DoubleVector, DoubleSparseVector) | Adds a dense vector to a sparse vector. The result is a dense vector. |
| Clone |
Creates a deep copy of this sparse vector.
(Overrides SparseVectorDataTClone) |
| Divide | Divides a sparse vector by a scalar. |
| Equals(Object) |
Equality of sparse vectors. Sparse vectors objects are equal if they have
the same nonzero elements.
(Overrides SparseVectorDataTEquals(Object)) |
| Equals(SparseVectorDataT) |
Equality of sparse vector data. Sparse vector data objects are equal if they have
the same nonzero elements.
(Inherited from SparseVectorDataT) |
| GetHashCode |
Gets the hash code for this instance.
(Overrides SparseVectorDataTGetHashCode) |
| Multiply(Double, DoubleSparseVector) | Multiplies a sparse vector by a scalar. |
| Multiply(DoubleSparseVector, Double) | Multiplies a sparse vector by a scalar. |
| Scale | Scales each element in the sparse vector by the specified value. |
 | SetData |
Sets the sparse vector data of self to the given values.
(Inherited from SparseVectorDataT) |
| Subtract | Subtracts a sparse vector from a dense vector. The result is a dense vector. |
| ToString |
String representation.
(Overrides ObjectToString) |
| ToString(String) | String representation with desired numeric formatting. |
| TwoNorm | Computes the Euclidean norm of the element of self. |
Operators| Name | Description | |
|---|---|---|
 | Addition(DoubleSparseVector, DoubleVector) | Adds a dense vector to a sparse vector. The result is a dense vector. |
| Addition(DoubleVector, DoubleSparseVector) | Adds a dense vector to a sparse vector. The result is a dense vector. |
