You repeatedly tell us, what you want to calculate. But you do not mention, what you have! x can be calculated, if you have H and x'. x' can be calculated, if you have H and x; H can be calculated, if you have x' and x. It is not possible to "calculate" x *and* H! It might be the best, if you describe your problem with more details. Please tell us the exact values or definitions, you want to base the calculations on. What are the conditions your x should satisfy? Kind regards, Jan |
