I have two columns in my dataset and I want the third column as a mean of two columns.  
I have achieved this result by writing code in java.  
But I wanted to calculated this using some ‘commons-math’ library. But I am unable to find any specific library for this.  
Below I have attached the link of the commons-math library for the reference.  
[http://commons.apache.org/proper/commons-math/](http://commons.apache.org/proper/commons-math/)

Can anyone know which class should I have to used for achieving this result…
