Hi.
I'm attempting to plot a function for the Current in a resistor-inductor circuit but am having no success in producing a proper graph. Why is this program not producing a graph with curves and only producing a straight line? Thanks

One possible explanation:
b=cos(omega*t*phi);
c=cos(phi)*exp(-t*R/L);
In these lines you use t, which is your upper bound on the time, rather than T, a vector containing each time point. As a result, I is a scalar corresponding to the current at the last time point.
b=cos(omega*T*phi);
c=cos(phi)*exp(-T*R/L);
Using these instead, I will be a vector with the same size as T which contains the current at each time point. If you want to plot current over time, you'll need to flip your arguments to plot:
plot(T, I)
