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?
running a loop from -INF to +INF with a small dx can take quite a long time. 🙂
Hint: You should rather use MATLAB or MATHEMATICA for such equations. Or paper and pencil…
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.
