MATLAB: Predict function doesn’t work in standalone Matlab application

Question

I have a code which uses both neural network and TreeBagger. I use nn(x) to calculate neural network output for given x. Also I use predict(TB,x) function to calculate the output of TreeBagger for given x. I made an application for above code which works very good. But, when I construct an standalone application, and run it, it makes error that bad use of predict. I guess that I must include machine learning toolbox to my app, or, I must use another approach to calculate predict(TB,x).

The app has No problem with nn (because it doesn't use predict), just error for TreeBagger and predict function.

I use MATLAB 2016b Application Compiler.

Answer 1

My suspicion is that you're bringing the TreeBagger object into your application by calling load on a MAT-file containing the object. Is that correct? If it is, see the Tip in the Fixing Callback Problems: Missing Functions section on this documentation page. Tell MATLAB Compiler that it needs to include the TreeBagger class in the standalone application using the option or the pragma listed in that section of that page.
