plot a smiley in matlab

To plot a smiley in MATLAB, we can use the viscircles function to draw two circles for the eyes and one circle for the mouth. We can then use the text function to add the smiley face and custom text.


main.m
% Define the center of the smiley
x = 0;
y = 0;

% Define the radius of the smiley
r = 5;

% Draw the eyes
viscircles([x-r/2, y+r/2], r/4, 'LineWidth', 2);
viscircles([x+r/2, y+r/2], r/4, 'LineWidth', 2);

% Draw the mouth
viscircles([x, y], r/2, 'LineWidth', 2);

% Add the smiley face and custom text
text(x-r/1.5, y+r/2, ':)', 'FontSize', 20);
text(x-r, y-r, 'I am a happy smiley!', 'FontSize', 12);
