Hi all,
For the last 3-4 days I have been working on the Jacobi Eigen Value
method. In the context of that method I have some doubts so as to how the does
DenseMatrix use the HTable to store data. Here is what my problem is.
>From the documentation I see that the Jacobi EigenValue method stores the
eigenvalues in another column of the original matrix. Tor retrieve these values
I
want to use some code of this sort
public static void main(String[] args) throws IOException {
Map blogpost = HBaseConnector.retrievePost("post1"); //Post1 is id of
a particular row
System.out.println(blogpost.get("post:title")); // Post:title is
the column family
System.out.println(blogpost.get("post:author"));
}
But I am unable to understand what values to use for the row- ids so that I can
retrieve the Eigen Values. Or is there any other method to retrieve these
values ?
