Overload List

DotProduct(Int32, Array1D<Complex<Double>>, Array1D<Int32>, ArraySlice<Complex<Double>>) Returns the dot product of a sparse and a dense vector.
DotProduct(Int32, Array1D<Double>, Array1D<Int32>, ArraySlice<Double>) Returns the dot product of a sparse and a dense vector.

DotProduct(Int32, Array1D<Complex<Double>>, Array1D<Int32>, ArraySlice<Complex<Double>>)

Returns the dot product of a sparse and a dense vector.
C# 
public override Complex<double> DotProduct(
	int n,
	Array1D<Complex<double>> x,
	Array1D<int> indx,
	ArraySlice<Complex<double>> y
)

Parameters

n  Int32
The number of nonzero elements in the vectors x and y.
x  Array1D<Complex<Double>>
A reference to a one-dimensional array containing the elements of the vector x.
indx  Array1D<Int32>
Integer array of component indices.
y  ArraySlice<Complex<Double>>
A reference to a one-dimensional array containing the elements of the vector y. The elements of y are overwritten with the result.

Return Value

Complex<Double>
