[jira] [Comment Edited] (SOLR-10753) Add array Stream Evaluator
[ https://issues.apache.org/jira/browse/SOLR-10753?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16026331#comment-16026331 ]

----------------------------------------------------------------
The array is really just designed to support vector math operations. The next step is a matrix which wraps arrays to support matrix math operations. I think it makes sense to keep these two structures focused on vector and matrix math.
The list is more of a general purpose container for Streaming Expressions.
If the function name array is too general, perhaps we can just go with vector or vec?
