naginterfaces.library.blas.dload

naginterfaces.library.blas.dload(n, con)

dload broadcasts a real scalar into a real vector.

For full information please refer to the NAG Library document for f06fb

https://support.nag.com/numeric/nl/nagdoc_30.2/flhtml/f06/f06fbf.html

Parameters

nint

$n$, the number of elements in $x$.

confloat

The scalar $\alpha$.

Returns

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

The elements $x_i$ of the vector $x$.

Raises

NagValueError

(errno $4$)

On entry, error in parameter $\text{incx}$.

Constraint: $\text{incx}>0$.

Notes

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

dload performs the operation

$$x\leftarrow {(\alpha ,\alpha ,\dots ,\alpha )}^T\text{,}$$

where $x$ is an $n$-element real vector.
