[jira] [Commented] (SYSTEMML-1626) x = solve(A,b) should report an
error when it is an underdetermined system (in CP mode)
[ https://issues.apache.org/jira/browse/SYSTEMML-1626?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16401151#comment-16401151 ]
Janardhan commented on SYSTEMML-1626:
-------------------------------------
Hi [~nakul02] , the method seems to be made for inspection of the matrices. Hence, the toString() priting the matrix in space separated format seem ok to me, instead of an error.
