I'm trying to plot a graph inside a loop for, because i have to increase g value then calculate L(inductance):
N=35;
Ac = 9*10^-4;
Ag=Ac;
lc = 30*10^-2;
ur = 70000;
u0 = 4*pi*10^-7;
x=0.0001:0.00001:0.001;
for g=0.0001:0.00001:0.001
Rc = (lc)/(ur*u0*Ac);
Rg = g/(u0*Ag);
Rtot = Rc+Rg;
L= N^2/Rtot;
plot(x,L,'-','LineWidth',2);
pause(.2)
end
But the popout of the plot show but nothing happen, can someone fix the code?

It seems like you want the drawing to be animated because you used pause(0.2) so try it this way:
clc; % Clear the command window.
close all; % Close all figures (except those of imtool.)
clear; % Erase all existing variables. Or clearvars if you want.
workspace; % Make sure the workspace panel is showing.
format short g;
format compact;
fontSize = 16;
N=35;
Ac = 9*10^-4;
Ag=Ac;
lc = 30*10^-2;
ur = 70000;
u0 = 4*pi*10^-7;
x=0.0001:0.00001:0.001;
allg=0.0001:0.00001:0.001
% Animate the curve drawing.
for k = 1 : length(allg)
g(k) = allg(k);
Rc = (lc) / (ur*u0*Ac);
Rg = g(k) / (u0*Ag);
Rtot = Rc+Rg;
L(k) = N^2 / Rtot;
plot(x(1:k), L(1 : k),'b.-','LineWidth',2, 'MarkerSize', 17);
grid on;
title('L vs. x', 'FontSize', fontSize);
xlabel('x', 'FontSize', fontSize);
ylabel('L', 'FontSize', fontSize);
pause(.2)
end
g = gcf;
g.WindowState = 'maximized'; pedro oliveira on 24 Oct 2021
thank you, thats a good ans for what i wanted
