Invisible in some contexts become visible in another. Because of private functions and subfunctions, functions that are.So this use of the which can help solve mysterious bugs. It's easy to accidentally obscure a system command by one of your own, Shows that one " plot" function obscures another (on my system anyway). Matlab will only run the first it finds but you can find out where other versions are. There may be several functions with the same name inĭifferent places.The which command can be used in more sophisticated ways than Of directories if you want but the default should be ok. You can find out which directories are searched and which order If that fails, then matlab searches directory after directory looking for.This private directory can only be called by files in the There's a subdirectory called private then the functions in If in the directory containing the original matlab file If there's no subfunction called foo matlab will look forĪ private function.A matlab *.mįile can contain several subfunctions. If it can't find a built-in function it will look in the matlabįunction file for a subfunction called foo.Then it will look for a built-in function.It will then look for a class member function.Firstly matlab will look for a variable called foo.Suppose in a matlab function file you have a

Source code may be online but more often isn't. Such files are operating-systemĭependent - Windows versions won't for example work on Macintoshes. MEX files are functions originally written a language like C++ or F90.Unlike *.m files these files aren't easy to read. These are *.m files that have been partly processed to make them run faster the first time they're called. " which fliplr" you'll find out where the fliplr.m " which plot" in a fairly recent matlab it will tell you that Some code is compiled into matlab itself.The function code itself can be in 4 main forms (and where the related code is) requires quite a good understanding of To understand exactly what gets run when you type a matlab function name
