can I generate c/c++ code from an m file function that uses a Mupad function ?

hi , I have an m-file that uses a Mupad function looks like following :

function fibret = myfibgen(x)

fibret = feval(symengine,'numlib::fibonacci',x)

which generates nth fibonacci number using the Mupad numlib::fibonacci function,it works perfectly in the matlab comand line however when I try to generate c/c++ code from it I get following error :

"??? The function 'symengine' is not supported for standalone code generation. See the documentation for coder.extrinsic to learn how you can use this function in simulation."

question : is what I'm trying to do possible but should be done otherwise or actually not doable at all ?

thanks in advance

The symbolic engine cannot be compiled and cannot have code generated for it.

There are numeric routines to generate Fibonacci numbers.

Caution: F78 is the largest value that fits as an integer in an IEEE 754 double precision number. F93 is the largest that fits in a 64 bit unsigned integer.
