Description
The
?copy
routines perform a vector-vector operation defined as y = x,
where
x
and y
are vectors.Input Parameters
- n
- Specifies the number of elements in vectorsxandy.
- x
- Array, size at least(1 + (.n-1)*abs(incx))
- incx
- Specifies the increment for the elements ofx.
- y
- Array, size at least(1 + (.n-1)*abs(incy))
- incy
- Specifies the increment for the elements ofy.
Output Parameters
- y
- Contains a copy of the vectorxifnis positive. Otherwise, parameters are unaltered.
