Introduction to the Live Editor
This example is an introduction to the Live Editor. In the Live Editor, you can create live scripts that
show output together with the code that produced it. Add formatted text, equations, images, and
hyperlinks to enhance your narrative, and share the live script with others as an interactive
document.
Create a live script in the Live Editor. To create a live script, on the Home tab, click New Live
Script.
Add the Census Data
Divide your live script into sections. Sections can contain text, code, and output. MATLAB code
appears with a gray background and output appears with a white background. To create a new
section, go to the Live Editor tab and click the Section Break button.
Add the US Census data for 1900 to 2000.
years = (1900:10:2000);
% Time interval
pop = [75.995 91.972 105.711 123.203 131.669 ...
% Population Data
150.697 179.323 213.212 228.505 250.633 265.422]
pop = 1×11
75.9950
91.9720 105.7110 123.2030 131.6690 150.6970 179.3230 213.2120 228.5050 250.6
Visualize the Population Change Over Time
Sections can be run independently. To run the code in a section, go to the Live Editor tab and click
the Run Section button. You can also click the blue bar that appears when you move the mouse to
the left of the section. When you run a section, output and figures appear together with the code that
produced them.
Plot the population data against the year.
plot(years,pop,'bo');
% Plot the population data
axis([1900 2020 0 400]);
title('Population of the U.S. 1900-2000');
ylabel('Millions');
xlabel('Year')
ylim([50 300])
