-------------------------------------
Summary: Add a SQL expression for ML vector affine transformations
Key: SPARK-59398
URL: https://issues.apache.org/jira/browse/SPARK-59398
Project: Spark
Issue Type: Improvement
Components: ML
Affects Versions: 5.0.0
Reporter: Ruifeng Zheng
Add an internal Catalyst expression that applies an element-wise affine
transformation to ML vector SQL representations. This provides a reusable
building block for future ML transform optimizations without changing ML
implementations in this issue.
