• Real-time updating plots using animatedline
Detailed Explanation
In this section, we discuss the use of animatedline in MATLAB for real-time data visualization. The animatedline function allows for the creation of plots that can update dynamically as new data is received. This is particularly useful in real-time signal processing where signals are continuously changing. By plotting the incoming data in real time, users can visually monitor the characteristics of the signal without needing to generate a static plot.
Examples & Analogies
Imagine you are watching a live sports event, where the scores change in real time. Just like the scoreboard updates immediately after every point is scored, using animatedline enables us to see changes in our data as they happen. It keeps spectators engaged and fully informed about the latest scenario, much like how we can keep track of signal variations as they occur in our plots.
