void GatherAndZero(
int n,
int m,
Span<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 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.
- 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.
