Subject [jira] [Created] (ATLAS-461) Larger Sparse Matrix implementation of OpenMapRealMatrix
Date Thu, 28 Jan 2016 15:55:39 GMT

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

             Summary: Larger Sparse Matrix implementation of OpenMapRealMatrix
                 Key: ATLAS-461
                 URL: https://issues.apache.org/jira/browse/ATLAS-461
             Project: Atlas
          Issue Type: Improvement
            Reporter: Eric Nelson
            Priority: Minor


In Apache Commons Math, the dimensions of OpenMapRealMatrix is restricted to numRows * numColumns
< Java's Integer.MAX_INT (2,147,483,647). Changing this to be stored as Longs would remove
this constraint. 

I am trying to use a slightly larger 50625 * 50625 sparse matrix but it's failing with
org.apache.commons.math3.exception.NumberIsTooLargeException: 2,562,890,625 is larger than,
or equal to, the maximum (2,147,483,647)
