From my understanding, 'place' function is not supported for code generation. Not all built-in functions are supported for code generation. You may find the list of built in functions for which code generation is supported here. There are two workarounds for this problem.
You may try implementing the built-in function in C/C++ or you may find a C/C++ program with the required functionality. Now, you may call the external C/C++ file using “coder.ceval()”.
You may declare the built in function as extrinsic using “coder.extrinsic()” function. During simulation, the code generator produces the code for the call to an extrinsic function but does not produce the function’s internal code.
