How can I solve system of equations in Labview?

[minmin2]

I want the values ​​of V1*, V3*

and values of K1,K2,K3,U1,U2,U3,U4,U5,a(x),a(y) was given 

so,

I wrote the code using the formula node as shown in the following figure, but it doesn't work.

You want to know how to calculate systems of quadratic equations using LabVIEW.

[minmin2]

I want to find the solution V1 V3 of the system of equations of F and G functions.

values of K1~K3, U1~U5, a(x), a(y) was already given

But I can't run it because it says error 1047

How should I solve it?

• Please attach your VI (containing typical default values in all controls). We cannot debug pictures.
• Please don't put regular body text into code tags.
• Please keep it all in one thread. I am sure there is no need for any script node (matlab or otherwise). I merged your two threads.
