Hello,
I need to perform some arithmetics between columns (i.e. multiplications, division etc. of one column by another) but could not find a node specifically for this purpose.
If this requires Java code, could anuýone help me getting started by providing me with the code for simply multiplying one column by another?
Thanks in advance!
Hi,
the Math Formula node from the Misc category might be the right choice for you. If it is not available you need to install the KNIME Math Expression (JEP) extension using the Install New Software... option from the Help menu. Select the KNIME update site from the available sites of the Work with setting. The Math Expression extension is available in the KNIME & Extensions category.
Bye,
Tobias
Excellent, just what I needed, works like a charm.
Many thanks for your swift response!
Giddyup!
