Type Parameters

T: The type of the nonzero elements. Either double or DoubleComplex

The SparseVectorDataT type exposes the following members.

Properties

	Name	Description
	Entries	Gets and set the non-zero entries.
	Indices	Gets and sets the non-zero entry's Indices.
	Item	Gets and sets the value at the given index.
	NumberNonZero	Gets an sets the number of non-zero elements.

Methods

	Name	Description
	Clone	Creates a deep copy of this sparse vector.
	Equals(Object)	Equality of sparse vector data. Sparse vector data objects are equal if they have the same nonzero elements. (Overrides ObjectEquals(Object))
	Equals(SparseVectorDataT)	Equality of sparse vector data. Sparse vector data objects are equal if they have the same nonzero elements.
	GetHashCode	Computes the hash code for self. (Overrides ObjectGetHashCode)
	SetData	Sets the sparse vector data of self to the given values.

Operators

	Name	Description
	Equality(SparseVectorDataT, SparseVectorDataT)	Tests for equality of two sparse vector datas. The datas are equal if they have the same nonzero elements.
	Inequality(SparseVectorDataT, SparseVectorDataT)	Tests for inequality of two sparse vector datas. The datas are equal if they have the same nonzero elements.

Fields

	Name	Description
	BLOCK_SIZE	Resiziable arrays will be allocated in blocks this size.
	entries_	Non-zero entries of the sparse vector.
	indices_	Indices of the non-zero entries such that the ith non-zero entry has index indices_[i].
	numNonZero_	Number of non-zero elements in the sparse vector.

Remarks

The nonzero elements of the vector are stored in a resizable array of type T and their corresponding indices are stored in a separate, parallel array of integers.
