TOPIC: What is the difference between Stakeholder matrix and Stakeholder Map?

Saw this in one of my reviewer questionnaires and was searching around for what they are, the explanations lead to pretty much the same thing - the mapping of the stakeholders in the 4 quadrant chart with their level of influence and interest. It seems the map can be more than that, but it mostly points to the 4 quadrants chart. Would anyone provide some more insight?
