MATLAB has lots of built-in functions that I can call, such as "sin" and "norm." However, some of MATLAB's built-in functions are part of different libraries that I cannot access directly. For example, the function "ssim" is part of MATLAB's image processing toolbox, so I cannot simply call "ssim" in my code and have it work.
How do I call built-in MATLAB functions that are in different libraries? Do I need to import the libraries somehow? If so, how do I do that? How do I do this for ssim specifically?
Thanks so much!
