Offset into y. - incy
- Type: SystemInt32
The increment for the array y. - x
- Type: SystemDouble
A reference to a one-dimensional array
containing the elements of the vector x.
- xOffset
- Type: SystemInt32
Offset into x. - indx
- Type: SystemInt32
Integer array of component indices. - indxOffset
- Type: SystemInt32
Offset into x.
