Using the built in math function block for the mod operation generates an expensive function call in the generated code.
I am using floating points and the desire is just to produce fmodf() as the result of code generation.
Anyone have any ideas? there do not seem to be any settings for this block related to CodeGen

using a C code function block or a state machine with the execution set to C language, the function "fmod" from the standard math.h library can used.
Not sure if there is a way to do it natively in MATLAB or simulink but this work around gets the job done
