问题
Equation is as shown:
Ii=7.5-1.1e-06*exp((Vv+0.3*Ii)/2)+(1.1e-06)-(Vv+0.3*Ii)/271;
How can I plot a graph of Ii
vs Vv
, given Vv
with a step size of:
Vv=0:1.5:35;
Would really appreciate any help thanks

You can use solve method:
Vv_arr = 0:1.5:35;
res_arr = [];
syms Ii
for Vv=Vv_arr
sol = solve(7.5-1.1e-06*exp((Vv+0.3*Ii)/2)+(1.1e-06)-(Vv+0.3*Ii)/271 - Ii == 0);
res = eval(vpa(sol));
res_arr = [res_arr res];
end
plot(Vv_arr, res_arr, 'LineWidth', 2);
grid on;
xlabel('Vv');
ylabel('Ii');
