How do I plot this on MATLAB

V(t)=100e^(-t/100u)*u(t-100u) The u next to the 100's is actually mu.

I cant figure out out to plot this. I tried V=100*exp(-10000*t).*heaviside(t-.0001) but it just spat out a straight line along 0.

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.

you can run it in a for loop (each time incrementing the value of t) , store the values of v in a vector and plot the vector. check the diffrent plotting option in matlab documentation.
