How I can solve this equation?

Hello.

I want to solve this problem but I do not know how to write (e^).

The Equation is here:

I want to plot n(t) for [0:4] and (J/Jth)=2.48 for [1:3]

Also I do not know write code for e^(t/trb).

Thank you.

The Variables are: n0 = 1.57 * 10^12 J/Jth = 2.48 trb = 1.98 tqw = 150

e^(whatever) is coded in MATLAB with the exp() function. E.g.,

exp(-t/trb)
