zhengruifeng opened a new pull request, #58805: URL: https://github.com/apache/spark/pull/58805
### What changes were proposed in this pull request? This PR follows up on #58626 by moving the `VectorDotProduct` implementation to the static `MLExpressionUtils.dotProduct` method. Both interpreted evaluation and generated code invoke the shared method. ### Why are the changes needed? The expression currently maintains separate Scala and generated Java implementations of the same dense and sparse vector dot-product logic. A shared static method removes this duplication and reduces the amount of generated code while retaining code-generated evaluation. ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested? ```text ./build/sbt 'catalyst/testOnly *VectorDotProductSuite' ./dev/lint-java ./dev/lint-scala ``` ### Was this patch authored or co-authored using generative AI tooling?
