Function M-Files, Part 2

  • Remember that function is the keyword, and a function file must start with that.
  • A function M-file may contain the code for more than one function. The first function in a file is the primaryfunction, and is the one invoked with the M-file name. Additional functions in the file are called subfunctions, and are visible only to the primary function and to other subfunctions.
  • You can use the pcode function to save the parsed version of an M-file for use in later MATLAB sessions, or by users from whom you want to hide your algorithms.
