10 equations with 10 unknowns

10 equations with 10 unknowns

10 equations with 10 unknowns



I have a problem with a system of 10 equations with 10 unknowns according to the sheet attached.

Mathcad says that he can not find a solution.
I changed estimated amounts (even complex) already as well as TOL and CTOL, but no improvement.

A system with each 2, 3, 4, 5 equations and unknowns is solved correctly, but with 6, 7 and 10 no solution can be found. With 8 and 9 I did not try yet.

Why does that not work?
Is there a syntax error?  Or are the equations not independent (but I think they are)?
Do you have an idea how I can solve this problem?
I use Mathcad 2000 Professional in german. If you send an attachment, please ensure that I can read it.

I just realize that I can not attach a Mathcad document to this message.
Can you give me an advise please????????

Many thanks in advance and best regards

You can't do attachments on eng-tips.com.  This sounds like one for the Mathcad Collaboratory.

Hi David
Thanks for your answer.
Who is "Mathcad collaboratory"? Do you know their E-mail- or internet address?
Many thanks and regards
