ScaleAndAddInPlace(Int32, Complex<Double>, ReadOnlySpan<Complex<Double>>, ReadOnlySpan<Int32>, Int32, Span<Complex<Double>>, Int32)
Evaluates a vector plus the product of a scalar and a sparse vector.
public override void ScaleAndAddInPlace(
int n,
Complex<double> alpha,
ReadOnlySpan<Complex<double>> x,
ReadOnlySpan<int> indx,
int m,
Span<Complex<double>> y,
int yStride
)
Parameters
- n Int32
- The number of elements in the vectors x and y.
- alpha Complex<Double>
- The scalar value used to multiply the elements of x.
- x ReadOnlySpan<Complex<Double>>
- 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<Double>>
- 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.
