Hi every one,
Is there any way to get the definite integration of a function? I need to do some calculations in my code which one of these is like "Integration of EXP(-x^2)dx from x=-inf to x=+inf". Can anyone please help me?
Thanks

LabVIEW does not do symbolic math. For questions like this, ask wolfram alpha, it even understands your question as written.
The answer is sqrt(pi), of course.

Thank you guys for your reply.
Actually I do not think I can use wolfram (or paper and pencil!) to do this. The integration I mentioned above was just an example of what I should do. In fact, it will be something like this: "EXP(-x^2)/(a^2+(b-x)^2) x=-inf to x=+inf" in which a and b are two constants (relative to x) related to pressure and temperature (which change continuously). So some parts of my code read the temperature and pressure and then should substitute their values inside this formula and finally get the tesult of the integral.
Thanks,

You simply use wolfram alpha again (or any other symbolic math tool) and it will give you the resulting formula in terms of a and b (need to upgrade to pro, though). Then program it in LabVIEW.
