integral of a function

Question

I have an ans for integral calculation

R = piecewise([1/(T*k) < 0, (E0/(T*k) - (E0*Inf)/(T*k))/(1 + Inf*(- infinity/(T*k) - 1))], [0 < real(1/(T*k)), E0/(T*k)])

the truth is in my situation

0 < real(1/(T*k))

is always true, therefore what I need is just the result as

E0/(T*k)

because this result need to be insert into another equation to be simplified, I hope I can tell MATLAB that

0 < real(1/(T*k))

is true or I can extract the term

E0/(T*k)

from the piece-wise function. Can anyone please tell me how can I do it, thanks a lot.

I suggest trying to use an assume() and then a simplify()

In Maple I would use

simplify(R) assuming 0 < real(1/(T*k))

that totally works, thanks a lot.
