Add math equations to a plot using LaTeX

This is an example of how to add LaTeX equations to plots in MATLAB®.

For more examples, go to MATLAB Plot Gallery

% Calculate the Fibonacci numbers from 1 to 12
fib = zeros(1, 12);
for i = 1:12
fib(i) = (((1+sqrt(5))/2)^i - ((1-sqrt(5))/2)^i)/sqrt(5);
end

% Plot the first 12 Fibonacci numbers
figure
plot(1:12, fib, 'k^-')

% Add a title and axis labels
title('Fibonacci Numbers from 1-12')
xlabel('n')
ylabel('F_n')

% Build a string that contains the Latex expression
eqtext = '$$F_n={1 \over \sqrt{5}}'; eqtext = [eqtext '\left[\left({1+\sqrt{5}\over 2}\right)^n -']; eqtext = [eqtext '\left({1-\sqrt{5}\over 2}\right)^n\right]$$'];

% Add the string containing the Latex expression to the plot
text(0.5, 125, eqtext, 'Interpreter', 'Latex', 'FontSize', 12, 'Color', 'k')
