Definition

Namespace: Numerics.NET.LinearAlgebra.Implementation
Assembly: Numerics.NET.SinglePrecision (in Numerics.NET.SinglePrecision.dll) Version: 9.0.0

Overload List

ScaleAndAddInPlace(Int32, Complex<Single>, ReadOnlySpan<Complex<Single>>, ReadOnlySpan<Int32>, Int32, Span<Complex<Single>>, Int32)

Evaluates a vector plus the product of a scalar and a sparse vector.
C# 
public override void ScaleAndAddInPlace(
	int n,
	Complex<float> alpha,
	ReadOnlySpan<Complex<float>> x,
	ReadOnlySpan<int> indx,
	int m,
	Span<Complex<float>> y,
	int incy
)

Parameters

n  Int32
The number of elements in the vectors x and y.
alpha  Complex<Single>
The scalar value used to multiply the elements of x.
x  ReadOnlySpan<Complex<Single>>
A reference to a one-dimensional array containing the elements of the vector x.
indx  ReadOnlySpan<Int32>
Integer array of component indices.
m  Int32
The length of the vector y.
y  Span<Complex<Single>>
A reference to a one-dimensional array containing the elements of the vector y. The elements of y are overwritten with the result.
incy  Int32
