Add Legend to Axes in MATLAB

% MATLAB code for adding legend to a 
% simple sine and cosine function plot
% Defining xrange
rng = linspace(-pi,pi,1000);    

% Plotting sine
plot(rng, sin(rng))

% Holding the earlier plot for simultaneous plotting
hold on        

% Plotting cosine
plot(rng,cos(rng))

% Adding legend, with same order as of plotting
legend('Sine','Cosine')

% MATLAB code for range 
rng = linspace(-pi,pi,1000);    

% Plotting sin^2
plot(rng, sin(rng).^2)
hold on

% Plotting cos^2
plot(rng,cos(rng).^2)

% Creating an array of character vectors
lgd = {'sine', 'cosine'};

% Converting the array into cell array
lgd=cell(lgd);

% Adding legend
legend(lgd)

% MATLAB code to add different legends to 
% multiple axes in the same figure.
rng = linspace(-pi,pi,1000);

% Defining two axes
ax1 = axes('Position',[0.05 0.05 0.5 0.5]);
ax2 = axes('Position',[0.6 0.6 0.35 0.35]);

% Plotting in each axes
plot(ax1, rng, sin(rng).^2)

% Plotting legend for axes 1
legend(ax1,'Sine')
plot(ax2,cos(rng).^2)

% Plotting legend for axes 1
legend(ax2,'Cosine')

% MATLAB code for changing the
% location of axes in the graph
rng = linspace(-pi,pi,1000);

% Plotting  curves
plot(rng, sin(rng))
hold on
plot(rng,cos(rng))
hold off

% Adding legend
lgd = {'sine', 'cosine'};
lgd=cell(lgd);
legend(lgd,'Location','north')
