How to reverse an Expression?

[Vairamuthu]

Hi All,

Is there a way to reverse an expression?

for eg., If my expression is A=X*Y+Z, Then I want to find the expression for X. (i.e. Output should be X=(A-Z)/Y ).

Any Help or Suggestions are highly appreciated.

Thanks,

Vairamuthu.

LabVIEW does not do symbolic math.

Just go to wolfram alpha, it will solve it

(just enter "solve A=X*Y+Z for X" and it will even tell you that Y cannot be zero for the solution).

altenback,

Thank you for your response.

Wolfram alpha is solving the exact thing that I want. But I want to be implemented in LabVIEW. Is there a way?

altenbach already gave you the answer; LabVIEW does not do symbolic math.

On the other hand, LabVIEW is a full featured programming language, so with sufficient effort you could build you own symbolic math engine. 🙂 Alternatively, you could build a parser that taps into a web based symbolic math service.

If you have an infinite amount of time and resources, and excellent programming skills, it could be done. 🙂

For one of the code contests I submitted code to call Wolfram Alpha from LV. Of course the voters decided that checking the weather was more interesting so I did not continue to update. My own development continued specifically to implement symbolic differentiation and more powerful plotting. Works great for auto generating curve fits without numeric differentiation. https://decibel.ni.com/content/docs/DOC-15420
