how do I solve simultaneous equation with 3 unknowns ?

[KDGREAT.]

I need to solve simultaneous equations with 3 unknowns . Can any body help out on how to go about this? Thanx.

You did not specify what kind of equations you have....

Are your equations linear? Check the linear algebra palette and a look at "solve linear equations:. 🙂

KDGREAT,

Altenbach makes available a great palette if you are wanting to use linear equations. The linear equations palette is within the mathematics palette in labview which also has a lot of other options for you to use. Those options are located in this link

I'm using student version of LABVIEW. From the inspection of the simultenous equations, they will involve both linear and quadratic. I will like to know the step by step procedure on how to implement the solution. Thanks.

The equations involve both linear and quadratic. Expecting your suggestions.

Thanks.

Ca you give an actual example for the set of equations?

[David_A]

Knowing how many of each equation types you will be dealing with will help this discussion further. It is hard to give you more details on the steps you want to accomplish without knowing a little more information.

Back to my first post, the mathematics post is what you want to look at. Two ways to get the implementation you are looking for are:

1. Linear Algebra --> Solve Linear Equations
2. Scripts and Formulas --> Zeroes --> Non Linear System Single Solution / Solver.

Than you all for your reply. There are three set of equations with 3 unknowns. Like I said ,the equation will involve both linear and quadratic. Can I implement this on LABVIEW student version? If yes how?. Hope this throws more light on the topic. Thanks.

What makes it so difficult for you to simply show a typical example of a set of equations instead of repeating what you already said? It would really help us understand the problem!

Try again! 🙂

the equation is in this form;

        4X = 2345 r............................(1

        6X + 4V + r = X-20r.................(2

        2X + R + V  = r + 2 V..............(3

   SOLVE FOR r,V and X.
