What can be done to reduce memory usage in MATLAB R2015b?

Has anyone else noticed that MATLAB version R2015b seems to use a lot more memory than R2015a (64 bit)? In my experiments, it seems to be using at least twice as much memory. So, for example, a program that used to use around 2.1 GB of memory is now using at least 4.6 GB. I've heard that the new MATLAB has a new execution engine and I wonder if that is part of the problem and what can be done about it. I'm also using the Image Processing Toolbox, so I suppose the problem could be in there. Any help is appreciated.

Are you creating a lot of graphics? If so what kind of graphics are you creating, and what steps are you taking to ensure they are deleted when finished with?

Hi, Actually, I'm not creating any graphics. The image processing functions are used on input images that are processed for certain kinds of features. The collected data is then output to a file, a support vector machine (exe) is called and the final results are written to another file.

Do you use/run code that is really data? For instance does some function generate MATLAB code files dynamically that are later run? If so then I suggest clearing the functions or scripts after running them with the clear command. Use clear myfunctionname not clear all for this.
