Function Replacement

Define code replacement mappings for functions

Use the Code Replacement Tool or programming interface to define code replacement mappings for math, memory, nonfinite, semaphore, mutex, lookup table, or your own custom functions. Control data alignment. Customize the code match and replacement process.
