Thank you. That's exactly what I was looking for.

I want to calculate the Hessian of a function that has 5 variables and 6 parameters. I do not want the derivatives taken by the parameters.

Is there a way to separately define parameters and variables in sage?

Alternatively, is there a way to make the Hessian function only use some variables for derivation?

Thanks for the reply. The problem wound up being much simpler to formulate and get the necessary values using lp_solve.

Hello, When using sagemath to compute a linear programming problem(using GLPK backend), is there a way to get the slack values other than the full p.print_ranges()? that is just send the slacks(surplus) to a variable or vector? Thanks.
