Exporting data from MATLAB to GAMS through GDX files
Hi all, I need some help to create a GDX from data I collected in MATLAB. Actually, I need to create a 'set' and a 'parameter'. The problem is that the current parameter is 'set' sized. e.g., the set 'j' has a dimension 1*100, while the parameter is par(i) I created the parameter in MATLAB as follow...

Re: Access to Hessian & Jacobian matrices at optimal point (IPOPTH)
I Michael, I really appreciate your help and support. I followed your instructions and it was successful. You know, I'm using GAMS V33.2. In this version, apparently, just by using the option 'hessian' it gives you the complete information for the Hessian and Jacobian matrices in a single GDX file. ...

Access to Hessian & Jacobian matrices at optimal point (IPOPTH)
Dear all, I'm looking for help for a queations that I've not found the solution. Actually, I'm working with NLP's, where I require to do sensitivity analysis. To do so, I need the information regarding the Hessian and Jacobian matrices. Increasing the print_level allows me to visualize this informat...
