MATLAB Data Import and Plotting Techniques

This video tutorial from the University of Edinburgh covers the process of importing and plotting experimental data in MATLAB. It begins with an introduction to data import methods, focusing on importing data from Excel files using MATLAB's import wizard. The tutorial then explains how to process and organize the imported data into variables, followed by steps to plot the data using MATLAB's plotting functions. The video also demonstrates how to annotate and customize plots, including adding labels, legends, and saving the plots in various formats for future use.
