matlab inductance

hi everybody

I'm trying to plot or show the instantaneous power on inductance...
I use a sine voltage v=100cos(wt) and L=50mH
this is the code I've entered in Matlab

t=0:0.00001:0.1;
v=100*cos(377*t);
x=2*pi*60*50E-3;

since PL=VmIm(sin2wt) and Vm=wLIm w=2Πf
I'll try to use the following eq. PL=((V^2)/wL)sin(2wt) to plot but no results...

I mean I want to plot the instantaneous power, the voltage and the current...

Do you have any idea...
thank's in avanced...
 

Dear,
do not think that the eq. posted for the power calculation is correct,
PL = v^2*sin(2*W*T)/WL where v is the Vm of the sin by following code is working, please check it.
t=0:0.00001:0.1;
w = 377;
L = 50E-3;
Vm = 100;
V=Vm*cos(w*t);
PL = Vm.^2.*sin(2*w*t)/(w*L);
plot(t,PL)
hold
plot(t,v)

hope it to be useful
