Following up, there are two external Matrix Libraries that I am familiar with (JAMA and Commons.Math3.Linear). Both of these libraries provide all the functionality necessary to emulate the Excel Matrix functionality. The Linear library is 2MB and JAMA is ~20KB. I understand this would be adding a dependency to the project. Is there a preference on which library would be used or is the preferred solution to implement the functionality directly in POI?
