Octave is a high-level language, primarily intended for numerical computations. A command-line interface (CLI) processes commands to a computer program in the form of lines of text. then use either from the command line, or in other functions or scripts. c++ - Get Lua command when calling AC function Supposed I register many different function names in Lua to the same function in C. Now, everytime my C function is called, is there a way to determine which function name was invoked? I'm not an Octave expert so there could be a way to get it to work where the file name is different, but file name and function name being the same should get you there.
