plot two functions in the same graph in matlab

main.m
% Define the x values
x = -10:0.1:10;

% Define the two functions
y1 = sin(x);
y2 = cos(x);

% Create a figure to hold the plot
figure;

% Plot the first function
plot(x, y1, 'b', 'LineWidth', 2);  % 'b' specifies blue color

% Hold on to the current figure to allow for multiple plots
hold on;

% Plot the second function
plot(x, y2, 'r', 'LineWidth', 2);  % 'r' specifies red color

% Add grid, labels, and legend
grid on;
xlabel('x-axis');
ylabel('y-axis');
legend('sin(x)', 'cos(x)');

% Title for the plot
title('Plot of sin(x) and cos(x) Functions');

% Hold off to stop further plots from being added to the same figure
hold off;
