Need to graph itt on Matlab ...

X= (V);

Y=(J);

V= linspace(0,1,500);

J= linspace(0,1,500);

for L=0.0005

for d=0.0005

for V=10*10^3

for lampda=1.5*10^-6

for n=1.51

for t= 10^-12

for Vpi= (d/L)*(lampa/t*n^3);

for thata0= 2pi*n*L/lampda

for thata= thata0 - pi* V/Vpi

for J=I0/Ii==cos^2((thata0/2)-(pi/2)*(V/Vpi))

polt figure (X,Y);
