programming in labview?

I don't think that giving a solution to what is obviously a homework question is in the best interest of the student. The student has not appeared to put any effort into learning even the basics.

Either that or the user is explaining what he wants incorrectly...

Going off the supposedly fixed values for R1 and Rf, the formula reduces to Vout = -Vin.  So... I don't even think there is a need to use LabVIEW 😛  However my ability to read electrical symbols is about as good as my ability to speak Klingon, so I figured I was missing something with the symbols that has more meaning that the equation printed below it.

That is true as long as the input and output voltages are within the supply voltage (assuming basic Op-Amp here, some will allow outside of the supply voltage).  But that would be another set of inputs for the In Range & Coerce.

The basic math problem that I noticed in his image was Vin-Vin. Not smarter than a fifth grader.

BUT this is where this type of simulation ends, because you can not limit the mathematical Vout like an Op-Amp's rail voltage will limit actual Vout in a circuit or a proper circuit simulation program would.

Anything can be simulated, given an appropriate mathematical model and a little bit more code. 😉

DOH! I always forget about In Range & Coerce...
