Help convert into a code

So I've been trying to plot this function as y achses and time t as x achses

t = 0 : 1/100 : 2*pi
u = 300*((exp(-t/(68.2128*10^-6))-(exp(-t/(405*10^-9)))))

but it doesn't seem to give me the correct answer. How can i convert the equation into a code?

I think your expression for u is ok (but note that 68.2128*10^-6 can be written more compactly as 68.2128e-6, etc., which allows you to use fewer parentheses). The only problem is the choice of t over which to calculate u.

t = 0 : 1e-6 : 4e-4;
u = 300*(exp(-t/68.2128e-6)-exp(-t/405e-9));
plot(t,u)
