Supported Matlab Functions in Simulink

Hello, I have a simulink simulation that is keeping track of the Julian Date through out the simulation.

At one point in the sim, I need to convert the Julian Date to a decimal year. The equivalent code in MATLAB would be:

decimal_year = decyear(Julian_Date - 1721058.5);

decyear is a built-in matlab function, however I'm getting an error saying that decyear is not valid for code generation.

I am aware that this is the case, however I do not need to generate any code involving the conversion and have since removed the %#codegen line in the embedded matlab function.

The problem is I'm getting the same error again. Is there anyway to solve this problem so I can use the decyear function in simulink?

Simulink needs to generate code for the MATLAB function block even in normal mode. You should refer to the list of supported functions http://www.mathworks.co.uk/help/simulink/ug/functions-supported-for-code-generation--alphabetical-list.html

Use coder.extrinsic if you do not need to generate code.
