Overload List

Gather(Int32, Int32, ReadOnlySpan<T>, Int32, Span<T>, ReadOnlySpan<Int32>) Gathers specific elements of a dense vector into a sparse vector.
Gather(Int32, Int32, ReadOnlySpan<Complex<T>>, Int32, Span<Complex<T>>, ReadOnlySpan<Int32>) Gathers specific elements of a dense vector into a sparse vector.

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

Gathers specific elements of a dense vector into a sparse vector.
C# 
public virtual void Gather(
	int n,
	int m,
	ReadOnlySpan<T> y,
	int yStride,
	Span<T> x,
	ReadOnlySpan<int> indx
)

Parameters

n  Int32
The number of elements in the vectors x and y.
m  Int32
The length of the vector y.
y  ReadOnlySpan<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.
x  Span<T>
A reference to a one-dimensional array containing the elements of the vector x.
indx  ReadOnlySpan<Int32>
Integer array of component indices.
