<zero-vector> ( exemplar -- zero )

Vocabulary

math.blas.vectors

Inputs

exemplar

a blas-vector-base

Outputs

zero	a blas-vector-base

Word description

Return a vector of zeros with the same length and element type as v. The vector is constructed with an inc of zero, so it is not suitable for receiving results from BLAS functions; it is intended to be used as a term in other vector calculations. To construct an empty vector that can be used to receive results, see <empty-vector>.
