naginterfaces.library.blas.zdotu

naginterfaces.library.blas.zdotu(x, y)[source]

zdotu computes the scalar product of two complex vectors.

For full information please refer to the NAG Library document for f06ga

https://www.nag.com/numeric/nl/nagdoc_28.7/flhtml/f06/f06gaf.html

Parameters
xcomplex, array-like, shape

The -element vector .

ycomplex, array-like, shape

The -element vector .

Returns
zducomplex

The value of the scalar product.

Notes

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

zdotu returns the value of the scalar product

where and are -element complex vectors.
