GitHub user rashmi815 opened a pull request:

    Unnest 2d array

    Array Operations: Add function to unnest 2-D arrays into rows of 1-D arrays
    JIRA:  MADLIB-1086
    Function to unnest 2-D array by one level (i.e. into rows of 1-D arrays).
    This is needed, for instance, in K-means, so that we can get one centroid per row for
follow on operations.
    - Added function to array operations
    - Added an example in k-means to demonstrate usage
