Set the type of a constraint
sym_setConstrType(index,type,bound1[,bound2])
This function completely modifies the type of a constraint. Supported types of constraints are less than or equal to, more than or equal to, equal to, or ranged.
The last argument is only required for ranged constraints. For the other types of constraints, only the third argument is required.
Index of the constraint to modify. Must be in {0,1,2,...n-1} where n is the number of constraints in the problem
New type of the constraint. Supported types: less than or equal to ("L"), greater than or equal to ("G"), equal to ("E"), or ranged ("R")
The first (or only) bound for the constraint
The second bound for ranged constraints. The two bounds for ranged constraints can be in any order.
