Calling User-defined Script from Java

I've installed R2017a and try to use Matlab Engine API for Java to run a user-defined script/function from Java.
The examples provided here(https://uk.mathworks.com/help/matlab/matlab_external/java-example-source-code.html) work perfectly fine. These examples, however, make use of Matlab package functions such as gcd, max etc.
I can't find any examples that enable to import and execute Matlab scripts (functions) defined by a user. Some examples for Python are provided here(https://uk.mathworks.com/matlabcentral/answers/322114-calling-script-from-python) but unfortunately, do not work in Java.
Any ideas how to achieve this functionality?

Hello,
You can call your function using 'eval'.
For example,
//Start MATLAB asynchronously
Future<MatlabEngine> eng = MatlabEngine.startMatlabAsync();
// Get engine instance
MatlabEngine ml = eng.get();
// Evaluate the command to cd to your function
ml.eval("cd path/to/funtion");
// Evaluate the function
ml.eval("myFunction(args)");

You have to specify the apostrophes properly when executing the command, similar to when executing it within the Matlab environment. For example,
// Start Matlab
Future<MatlabEngine> engine = MatlabEngine.startMatlabAsync();
MatlabEngine eng = engine.get();
// Change directory and evaluate your function
eng.eval("cd 'path/to/your/function'");
eng.feval("yourFunction", param1, param2, ...);
