Hi,
can someone help me to copy this mathcad code in a SMath's one?
I have some problems with the solution of Xn
Thank you

Hi. sigma.c fucntion is defined with an if clause. SMath can't integrate it, but you can use cases():
Now you can integrate:
Best regards.

Thanks Alvaro.
I made your correction, using the function cases(), but I have the same problem if I add other terms to fb(xn), for example if I add Ast*sigma sb(eps) and Asc*sigmasb(eps).
How is it possible?

Possibly an odd bracket problem?
Here appears that Smath is making a group of "y+sigma bla bla" as object for the differential operator
So, fb(x) could not be evaluated.
I placed some brackets to clearly separate "y" from what follows in the equation, see picture below.
It appears that with brackets, fb(x) can be evaluated (but I get an error on units).
Maybe some other formula needs to be checked before?
Ciao!

Splitted the equation in three contributions, it appears the the integral is not consistent with other two terms of the sum
I think calculation should work, once you clear the unit issue which is hidden somewhere in other parts of the calculation.
Ciao

I am pretty sure my units mismatch correction is not suitable.
You should have to check this issue by yourself.
But I had managed to solve your function problem.
Rewriting it make function tick again.

I've had this pending in background so I'll share the solution even here. Aside the initial issues about if() and units, the integral fails when x_n is set as 0, since epsilon is something/0. Therefore solve range must exclude 0 or the function has to handle it.
Happy Easter and take care, anyone.
