             Summary: Change normalize function to standardize and make it work 
with matrices
                 Key: SOLR-11599
                 URL: https://issues.apache.org/jira/browse/SOLR-11599
             Project: Solr
          Issue Type: New Feature
      Security Level: Public (Default Security Level. Issues are Public)
            Reporter: Joel Bernstein


It seems that the *normalize* function, which converts a vector to a mean of 0 
with a std of 1, is more typically called *standardize*.  This ticket changes 
the name of the function and allows it to work on matrices as well as vectors.
