Subject: Biproportional Matrix Balancing and RAS Procedures From: Gregory Date: 23 Jun, 2010 00:20:16 Message: 1 of 5 
I am looking for MATLAB functions that implement a procedure called "Biproportional Matrix Balancing" which is also referred to as "RAS". The technique adjusts the elements of an arbitrary matrix so that the row and column sums of the matrix equate to usersupplied initial "control total" or "margin" row and column vectors. The RAS technique is commonly applied to economic inputoutput matrices as a way of updating an interindustry transactions matrix from one year to the next. I have found several examples of RAS programs using GAMS but I'm hoping someone has implemented RAS for MATLAB to spare me the job of writing my own code.

do you have a solution for your problem I try to do an algorith for RAS but I donĀ“t have succes. If you have implemented RAS for MATLAB can you help me?

HI Greg, there has been a discussion on this topic some years ago.
