        x : Array1D<'T> * 
        indx : Array1D<int> * 
        y : ArraySlice<'T> -> 'T

n Int32: The number of elements in the vectors x and y.
x Array1D<T>: A reference to a one-dimensional array containing the elements of the vector x.
indx Array1D<Int32>: Integer array of component indices.
y ArraySlice<T>: A reference to a one-dimensional array containing the elements of the vector y. The elements of y are overwritten with the result.
