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?

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