Python language in Matlab "No appropriate method, property, or field"

In the Python Shell the following command (used to pilot the Digsilent Powerfactory software) works fine: app.GetFromStudyCase("ComLdf"). However, I am not able to identify a suitable translation for this command within the Matlab environment. For example, using the syntax app.GetFromStudyCase('ComLdf'), Matlab gives the following error: "No appropriate method, property, or field 'GetFromStudyCase' for class 'py.powerfactory.Application'."
Any suggestion?
Thank you in advance for your support.

What type of attribute is 'GetFromStudyCase'? Is it an instance method, static method, etc? One way to check is to look at the display. What does the following command display?
>> py.getattr(app, 'GetFromStudyCase')
Here are a few workarounds to try:
1. Use eval to call the method.
py.eval('app.GetFromStudyCase("ComLdf")', struct('app', app))
2. Use feval to invoke the instance method object.
methodObj = py.getattr(app, 'GetFromStudyCase');
feval(methodObj, 'ComLdf') % starting in R2015a, the syntax methodObj('ComLdf') should work
3. Use py.operator.methodcaller to call the method.
f = py.operator.methodcaller('GetFromStudyCase', 'ComLdf');
feval(f, app) % starting in R2015a, the syntax f(app) should work
