[jira] [Updated] (SPARK-5301) Add missing linear algebra utilities to IndexedRowMatrix and CoordinateMatrix

     [ https://issues.apache.org/jira/browse/SPARK-5301?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Reza Zadeh updated SPARK-5301:
------------------------------
    Description: 
1) Transpose is missing from CoordinateMatrix (this is cheap to compute, so it should be there)
2) IndexedRowMatrix should be convertable to CoordinateMatrix (conversion method to be added)
