File Infrastructure and Paths Setup

Compile Path Search Order

fiaccel resolves function calls by searching first on the code generation path and then on the MATLAB^® path. By default, fiaccel tries to compile and generate code for functions it finds on the path unless you explicitly declare the function to be extrinsic. An extrinsic function is a function on the MATLAB path that is dispatched to MATLAB software for execution. fiaccel does not compile extrinsic functions, but rather dispatches them to MATLAB for execution.

Naming Conventions

MATLAB enforces naming conventions for functions and generated files.

Reserved Prefixes

MATLAB reserves the prefix eml for global C functions and variables in generated code. For example, run-time library function names all begin with the prefix emlrt, such as emlrtCallMATLAB. To avoid naming conflicts, do not name C functions or primary MATLAB functions with the prefix eml.

MATLAB Coder™ software reserves certain words for its own use as keywords of the generated code language. MATLAB Coder keywords are reserved for use internal to MATLAB Coder software and should not be used in MATLAB code as identifiers or function names. C reserved keywords should also not be used in MATLAB code as identifiers or function names. If your MATLAB code contains reserved keywords that the code generator cannot rename, the code generation build does not complete and an error message is displayed. To address this error, modify your code to use identifiers or names that are not reserved.

If you are generating C++ code using the MATLAB Coder software, in addition, your MATLAB code must not contain the C++ Reserved Keywords.
