naginterfaces.library.blas.dcopy

naginterfaces.library.blas.dcopy(x)

dcopy makes a copy of a real vector.

For full information please refer to the NAG Library document for f06ef

https://support.nag.com/numeric/nl/nagdoc_30/flhtml/f06/f06eff.html

Parameters

xfloat, array-like, shape $\left(n\right)$

The $n$-element vector $x$.

Returns

yfloat, ndarray, shape $\left(n\right)$

The elements $y_i$ of the vector $y$.

Notes

No equivalent traditional C interface for this routine exists in the NAG Library.

dcopy performs the operation

$$y\leftarrow x$$

where $x$ and $y$ are $n$-element real vectors.
