protected function Recommender::prepareData in Recommender API 6.2

After calling this function, data would be ready to process. Could be: 1) if it's in database, then $->tableName, $this->$field* would store the correct info. 2) if it's in memory, then $this->directMatrix will be the matrix

Parameters

$performance could be 'memory' or 'database':

$missing could be 'none' or 'zero'.:
