The seven variables you are solving for should not be arguments of the function and you should not use any row or column selectors.

It should look that way

and while you still would get the message that the results can't be displayed, you should be able to use the function numerically like

Unfortunately for reasons unknown to me the calculations seems to run endless and so this seems not to work.

 

But there are good news. While the full 1x7 result row vector is (in the opinion of Prime) to large to be displayed, the results can displayed one by one:

EDIT: Actually I have no idea what the problem with evaluation Test(1,2,3,4,5,6,7) would be.

After all, Prime can quickly and easily find a solution that way:

If you can fix omega_s then Mathcad return the answer.
So, maybe you need one more equation to solve.

So, for now ws need to be defined as symbolical variable. I have 7 unknown variables (iL1s, iL1c, iL2s, iL2c, vC1s, vC1c, vCF) and also 7 equations, therefore should not be a problem with this thing...I mean in such a way that we need to assign for ws (or other variable) a (starting) value or to add more equation(s).

For example, Mathcad 11 can solve this system of equations as it is...without any problem.

Given the error message Prime is also able to solve the system - it just refuses to display the result. MC11 could be modified so that it also shows very large symbolic results, but later Mathcad version and also Prime can not be modified that way.

You may follow the advice and assign the result a variable, or better, a function in omega.s, C1, L1, etc. which you then can use for further calculations.
