% Define parameters
PopSaudi22
P_0 = PopSaudi22.POPTOTL % Initial population (1 million)
r = 0.02; % Annual growth rate (2%)
t = 1:1:20; % Time in years from 0 to 50 with a step of 0.1
% Compute population over time
P = P_0 * exp(r * t)
% Plot the result
figure;
plot(t, P,'-o', 'LineWidth', 2);
xlabel('Time (years)');
ylabel('Population in million');
title('Exponential Population Growth');
grid on;

P_0 = 1e6; % Initial population (1 million)
r = 0.02; % Annual growth rate (2%)
t = 0:0.1:50; % Time in years from 0 to 50 with a step of 0.1
% Compute population over time
P = P_0 * exp(r * t)
% Plot the result
figure;
plot(t, P/1e6,'-o', 'LineWidth', 2);
xlabel('Time (years)');
ylabel('Population in million');
title('Exponential Population Growth');
grid on;
ax = gca();
yt = get(ax,'YTick');
ax.YTickMode = 'manual';
ax.YTickLabel = yt+"m";
