Hello. I am trying to save the texture features that I extracted from an image in a .mat file and set it as my training dataset. I wanted to save each and every texture features that I extracted everytime I process an image to that same .mat file. How can I do it? Or do you have any code that can help me to get it? I read about"append" but it replaces the values with same variables. Please, I appreciate your help on this one.
