How to compute "det" function for input of type function handle or baronvec?

Hi everyone,

I need your help regarding the following issue:

I am dealing with BARON solver through BARON/ matlab interface. and I am facing difficulty in writing the non linear constrain where I need to use the det function for function handler or baron vector (barvec) matrix. So is there any way to do it ?

your help is much appreciated.

Many thanks,
Sara
