You have an Octave function
and you want to move it into a separate file.
First, you need to know that a function file can only contain ONE function and that function needs to be named just like the file.
Therefore, if your function is called myfunc
, you absolutely need to move it to a file called myfunc.m
, or else Octave won’t find it.
Creating the file is pretty simple: Just paste the function into the file. You must ensure that the first statement in the file is function ...
(else, it will be treated as a script file
, not a function file) (any number of comments and empty lines is OK though)
Example: myfunc.m
:
function retval = myfunc(n) retval = n + 5 endfunction
After you have saved that file, you can immediately use myfunc()
in Octave:
>> myfunc(3) retval = 8 ans = 8
Octave will automatically use the updated version in case you make changes to myfunc.m
