The method 'empty' is not supported for code generation. What can I do?

Hello!

I would like to generate c++ code from Matlab with Matlab Coder. When I click on "build" the Coder says:

The method 'empty' is not supported for code generation.

 bs_ek = BS.empty();

The BS is a simple Handle class.

How can I solve this problem?

Thank you in advance!

What is the empty() method? Could you post the sample class?
