Simulink function with bus output fails to run

2 views (last 30 days)
Goodmorning,
I have a problem when calling a Simulink function from for example a chart or a matlab function when it has a bus output. Documentation says bus outputs are supported for Simulink functions, but running fails when the function is called. The error is:
c3_untitled.c(399): error C2224: left of '.a' must have struct/union type c3_untitled.c(400): error C2224: left of '.a1' must have struct/union type NMAKE : fatal error U1077: '"C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\Bin\amd64\cl.exe"' : return code '0x2'
I included a simple model showing the problem in the attachment.
Thank you for your time and support.

Apparently this is an error in specific related to MATLAB 2016b. If the output of an exported function is a bus, the output of the function must also be defined as an input or output of the chart. Otherwise it will not work.
In versions earlier or later this might not be a problem.
