### fixing a non square system in CNS

Posted:

**Sun Feb 10, 2019 7:09 am**Hi

I am working on a CGE model. I received this message

********************************************************************************

**** ERROR: CNS models must be square

This model contains 3270 equality rows and 3274 unfixed columns

MODEL STATISTICS

BLOCKS OF EQUATIONS 105 SINGLE EQUATIONS 3,270

BLOCKS OF VARIABLES 96 SINGLE VARIABLES 3,274

NON ZERO ELEMENTS 15,180 NON LINEAR N-Z 7,319

DERIVATIVE POOL 20 CONSTANT POOL 1,367

CODE LENGTH 20,968

SINGLE =E|X= EQUS 3,270 SINGLE UNFIXED VARS 3,274

*********************************************************************

How I could find the extra variables and fix the problem?
