naginterfaces.library.blas.zdotc

naginterfaces.library.blas.zdotc(x, y)

zdotc computes the scalar product of two complex vectors.

For full information please refer to the NAG Library document for f06gb

https://support.nag.com/numeric/nl/nagdoc_30/flhtml/f06/f06gbf.html

Parameters

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

The $n$-element vector $x$.

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

The $n$-element vector $y$.

Returns

zdccomplex

The value of the scalar product.

Notes

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

zdotc returns the value of the scalar product

$$x^{H}y$$

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