The @ symbol in MATLAB represents a function handle, which allows users to create anonymous functions. In the context of the quad command, it is used to define the function to be integrated. For example, using the command y = @(x) x^2 defines a function y that squares its input. This functionality is essential for performing numerical integration in MATLAB.
