Please do not post the same question twice. It won't get you any more answers and just leads to confusion because whatever answers you do get may be split between two threads.
Not everyone can read Prime 3.1 format, so could you also post a pdf of the Mathcad worksheet showing what you have done.
You wanted to "Help me to programming the numerical method", which I think I did. And you were able to replicate what I did in Mathcad 11 into Prime 3.1.
I think it's up to you now to change the formulae to your more detailed need, and get the results you want.
If you then run into specific problems, don't hesitate to come back for help.
