can somebody tell me how I generate this project?

[Iulia_Molly]

I'm trying to generate the roots of this equation an · xn + an−1 · xn−1 + . . . + a1 · x + a(0) = 0

This is fairly straight-forward, all you need to do is build the equation into a polynomial from an array using ascending power order i.e. x^3 - 2x^2 + 4x -9 = 0 becomes [-9, 4, 2, 1]. 

Once you have done that feed the array into the "Polynomial Roots.vi" in order to get an array of the roots.

I just started to learn labview and I really don't know how to do that polynom so please help me with a specific i.e !! 

[ogk.nz]

press 'ctl + space" and type in "Polynomial root". Either that or in the block diagram right-click the background, then go Mathematics -> Polynomial -> Poly Roots

[Iulia_Molly]

Coudl you please solve that equation! I really don't get it right now!

[Iulia_Molly]

Okay ! I am trying right now!

[Iulia_Molly]

HMMM... I already done that!

You already have an array of coefficients set up within the cluster control.

Now you just need to read the help for the Polynomial Roots VI to learn how to use it and apply that array of coefficients to it.

If you change your output array from a DBL to a Complex double it should work better. To do this, right click the terminal for the array and go Representation -> Complex Double (CDB)
