Hi Werner.
I have a question. I want to restrick " a,a' " to keep 0<a<1 ,0<a'<1.
it means that inital guess is 0<a<1 ,0<a'<1.
The initial guess? Think you mean the solution should be in this range.
You would simply have to add the two constraints 0<a<1 ,0<a'<1 in the solve block.
But if Prime can't find a solution the solve block will fail. Sometimes it may help to change the guess values.
Are you sure that your system has multiple solutions and that always one will be in the desired range?
