MATLAB is an amazing product that helps you perform math-related tasks of all sorts using the same techniques that you’d use if you were performing the task manually (using pencil and paper, slide rule, or abacus if necessary, but more commonly using a calculator). However, MATLAB makes it possible to perform these tasks at a speed that only a computer can provide. In addition, using MATLAB reduces errors, streamlines many tasks, and makes you more efficient. However, MATLAB is also a big product that has a large number of tools and a significant number of features that you might never have used in the past. For example, instead of simply working with numbers, you now have the ability to plot them in a variety of ways that help you better communicate the significance of your data to other people. In order to get the most from MATLAB, you really need a book like MATLAB For Dummies.
