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 vectors x and y.

x

Array, size at least (1 + (n-1)*abs(incx)).

incx

Specifies the increment for the elements of x.

y

Array, size at least (1 + (n-1)*abs(incy)).

incy

Specifies the increment for the elements of y.

Output Parameters

y

Contains a copy of the vector x if n is positive. Otherwise, parameters are unaltered.
