2014-08-11 14:58:23 +0100 | asked a question | Specifying variables to be included in Hessian calculation 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? |

2013-07-15 09:17:24 +0100 | asked a question | How to get slack values when using GLPK backend? 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. |
