A function file may contain secondary functions called subfunctions. These secondary functions are only visible to the other functions in the same function file. For example, a file f.m containing
function f () printf ("in f, calling g\n"); g () endfunction function g () printf ("in g, calling h\n"); h () endfunction function h () printf ("in h\n") endfunction
defines a main function
f and two subfunctions. The
h may only be called from the main
f or from the other subfunctions, but not from outside
the file f.m.
Return a list of all local functions, i.e., subfunctions, within the current file.
The return value is a column cell array of function handles to all local
functions accessible from the function from which
called. Nested functions are not included in the list.
If the call is from the command line, an anonymous function, or a script, the return value is an empty cell array.
Compatibility Note: Subfunctions which contain nested functions are not included in the list. This is a known issue.
