-------------------------------------

             Summary: Add grandSum, sumRows, sumColumns, scalarDivide, scalarMultiply, scalarAd, scalarSubtract Stream Evaluators
                 Key: SOLR-11607
                 URL: https://issues.apache.org/jira/browse/SOLR-11607

          Issue Type: New Feature
      Security Level: Public (Default Security Level. Issues are Public)
            Reporter: Joel Bernstein


This ticket adds a set of matrix math functions:

grandSum: sum of all the values in a matrix
sumRows: returns a vector with sums of all rows
sumColums: returns a vector with the sums of columns
scalarAdd: add a number to each entry in the matrix, returns s new matrix
scalarSubtract: subtracts a number from each entry in the matrix, returns a new matrix
scalarMultiply: multiplies a number to each entry in the matrix, returns a new matrix
scalarDivide: divides each entry in a matrix by a number, returns a new matrix
