Calling other function from another m file

You may notice that a function will still work as expected if you change the name of the main function to no longer match the file name. Problems will start occurring if you put your main function after the first function (this will throw an error or simply not execute).

The mere fact you want to call this subfunction means that it deserves to be a separate function, as it apparently simply an implementation detail for the main function in the file.

Only the main function in a function file is directly callable from outside the file. Local functions can be called indirectly if you have a function handle to the local function. In order to do this the function handle would need to be created inside the main function and returned from it.

Is there an example of this?

在 MATLAB Online 中打开

main_function.m

@Dharmesh Joshi: See the attached m-file for a simple example of this.

f = main_function
f = function_handle with value:
    @local_function
f(4)
ans = 4
