vec:add( $vector1 as vec:vector, $vector2 as vec:vector ) as vec:vector
Summary
Returns the sum of two vectors. The vectors must be of the same dimension.
| Parameters | |
|---|---|
| vector1 | The first addend vector. |
| vector2 | The second addend vector. |
Example
xquery version "1.0-ml"; let $vec1 := vec:vector((3.14,1.59,2.65)) let $vec2 := vec:vector((3.58,9.79,3.23)) return vec:add($vec1,$vec2); => [ 6.72, 11.38, 5.88 ]
Example
xquery version "1.0-ml";
let $vec1 := vec:vector(fn:head(fn:doc('pronethalol.json'))/data/array-node{embedding})
let $vec2 := vec:vector(fn:head(fn:doc('cell_renewal.json'))/data/array-node{embedding})
return vec:add($vec1,$vec2)
=> The sum of vectors in JSON arrays named 'embedding'
in documents 'pronethalol.json' and 'cell_renewal.json'
