NMathFunctionsDot(FloatSparseVector, FloatVector) Method

Calculates the dot product of a sparse vector and a dense vector.

Namespace: CenterSpace.NMath.Core
Assembly: NMath (in NMath.dll) Version: 7.4
Syntax
public static float Dot(
	FloatSparseVector w,
	FloatVector v
)

Parameters

w  FloatSparseVector
A sparse vector.
v  FloatVector
A dense vector. The length of this vector must accomodate the largest index of the largest nonzero value in the sparse vector. Specifically v.Length must be greater than max{indices of nonzero value in w} + 1.

Return Value

Single
The dot product.
Exceptions
ExceptionCondition
InvalidArgumentException Thrown if v or w has zero length, or the length of v is less than the maximum nonzero index in w + 1.
Remarks
d = v[0]w[0] + v[1]w[1]...
