    [Spark-6693][MLlib]add tostring with max lines and width for matrix · 9c67049b

    jira: https://issues.apache.org/jira/browse/SPARK-6693
    
    It's kind of annoying when debugging and found you cannot print out the matrix as you want.
    
    original toString of Matrix only print like following,
    0.17810102596909183    0.5616906241468385    ... (10 total)
    0.9692861997823815     0.015558159784155756  ...
    0.8513015122819192     0.031523763918528847  ...
    0.5396875653953941     0.3267864552779176    ...
    
    The   def toString(maxLines : Int, maxWidth : Int) is useful when debuging, logging and saving matrix to files.

    420da39 [Yuhao Yang] Merge remote-tracking branch 'upstream/master' into addToString
