Create Matrix from Loop of Vectors, Sort It and Pick Top-K
Hi,
I have the following dataset (simplified for example).
__DATA__
300.35 200.25 104.30
22.00 31.12 89.99
444.50 22.10 43.00
22.10 200.55 66.77
Now from that I wish to do the following:
1. Compute variance of each row
2. Pick top-2 row with highest variance
3. Store those selected rows for further processing
To achieve this, I tried to: a) read the table and compute
variance for each row,
