Hi,

No, but my question is how I can order 12 of these equations to get a solution for this system?

Thank you

@Preben Alsholm 

You can just forget the Ll, id0, iq0 and the first 4 equations I have to determine those 8 variables around the initial guess

Yes but if you delete the first four and use the last  equations still I don't get any good solution

@Axel Vogt 

I have to resolve it to find the c,d,e,... parameters, that's all

exact numbers you mean instead of 5,1234..should I use 5..or?

And then what can I do? In order to get a solution

But how I can use that one for two vectors, you can see my first  post.

I mean I have an excel file with two columns the first one is the mag and the second one is the angle in degrees.

So I need to plot it a compass form with arrows, maybe you can offer me an example for this.

Thank you very much
