This example shows how to use the setTflCFunctionEntryParameters function to set specified parameters for a code replacement function entry for sqrt. fcn_entry = RTW.TflCFunctionEntry; fcn_entry.setTflCFunctionEntryParameters( ... 'Key', 'sqrt', ... 'Priority', 100, ... 'ImplementationName', 'sqrt', ... 'ImplementationHeaderFile', '<math.h>' );
