ScaleAndAddInPlace(Int32, T, ReadOnlySpan<T>, ReadOnlySpan<Int32>, Int32, Span<T>, Int32) Evaluates a vector plus the product of a scalar and a sparse vector.
ScaleAndAddInPlace(Int32, Complex<T>, ReadOnlySpan<Complex<T>>, ReadOnlySpan<Int32>, Int32, Span<Complex<T>>, Int32) Evaluates a vector plus the product of a scalar and a sparse vector.

ScaleAndAddInPlace(Int32, T, ReadOnlySpan<T>, ReadOnlySpan<Int32>, Int32, Span<T>, Int32)

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

Parameters

n  Int32
The number of elements in the vectors x and y.
alpha  T
The scalar value used to multiply the elements of x.
x  ReadOnlySpan<T>
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<T>
A reference to a one-dimensional array containing the elements of the vector y. The elements of y are overwritten with the result.
yStride  Int32
The distance between successive elements in y.
