Matlab AMPL ConstraintInstance.restore用法及代码示例

ampl.eval('var x{1..3}<=4;');
ampl.eval('maximize z: sum{i in 1..3} x[i];');
ampl.eval('c {i in 1..3} : x[i] <= i;');
c2 = ampl.getConstraint('c').get(2);
x = ampl.getVariable('x');

c2.drop;
ampl.solve;
x.display

c2.restore;
ampl.solve;
x.display

x [*] :=
1  1
2  4
3  3
;


ans =

x [*] :=
