Commenting on my own question: I should also point out that when I use Ctrl-C to stop the script, memory is not freed and when I try to exit MATLAB it spends a lot of time -- several minutes -- cleaning up memory before it finally exits (if it exits at all).
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?

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.
