    Hi,

    I don't think there is an operator to do it, but nonetheless there are several ways. The most efficient one inside RapidMiner would be to write a Groovy script (operator Execute Script). R/Python could also be used but could be much slower if the matrices are big. In R/Python it's literally one line of code.

    What is the use case?
