A guess:
ustp = @(t) t>0; % Unit Step Function
mu = 100;
V = @(t) 100*exp(-t/(100*mu)).*ustp(t-100*mu);
t = linspace(0, 1E+5);
figure
plot(t, V(t))
grid
I understand that ‘u’ as a variable is μ, however your using the heaviside function seems to indicate that one of the ‘u’ uses is the unit step function operator.
