Large Hessian matrix not displayed

Hello,

I am trying to calculate the Hessian of a symbolic determinant with respect to 12 symbolic variables. Then creat a matlabFunction of the resulting Hessian to use the block in Simulink. My concern is:

- Is is realistic to have a 12x12 Hessian

- Matlab does calculate the 12x12 Hessian but the Command Window does not display the result of the symbolic Hessian.

- The matlabFunction instruction takes ages and doesn't even calculate it as i always stop it after a few hours.

Do you have any instructions or comment. I really need your help. Thank you :)

Regards.
