Try this:
% Initialization / clean-up code.
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 long g;format compact;fontSize = 20;theta = linspace(-pi, pi, 1000);period = 3*pi/4; % Whatever you want.
sint = sin(2 * pi * theta / period);plot(theta, sint, 'b-', 'LineWidth', 2);hold on;cosinet = cos(2 * pi * theta / period);plot(theta, cosinet, 'r-', 'LineWidth', 2);tant = tan(2 * pi * theta / period);plot(theta, tant, '-', 'Color', [0, 0.5, 0], 'LineWidth', 2);grid on;xlabel('Theta [in radians]', 'FontSize', fontSize);ylabel('Amplitude (signal value)', 'FontSize', fontSize);title('Trig functions versus Theta', 'FontSize', fontSize);legend('Sine', 'Cosine', 'Tangent');% The tangent spikes are so big that we can't see the sin and cosine.
% Let's limit the y range to +/- 4;
ylim([-4, 4]);% Set up figure properties:
% Enlarge figure to full screen.
set(gcf, 'Units', 'Normalized', 'OuterPosition', [0 0 1 1]);% Get rid of tool bar and pulldown menus that are along top of figure.
set(gcf, 'Toolbar', 'none', 'Menu', 'none');% Give a name to the title bar.
set(gcf, 'Name', 'Demo by ImageAnalyst', 'NumberTitle', 'Off')
