MATLAB: Script with all my functions -

maybe it's basic question here go. have .m functions accessed other scripts , functions.

i tried doing script functions , call in other functions code.

and got , error. please explain me how can solve this?

i'm trying this, gives me no error, , want do, still, way it? suggestions?

function pruebasllamafuncion     funcionfem=@pruebastodasfunciones;     a=funcionfem('overpower',1,5)     b=funcionfem('poweroverwelming',2) end  ...     function a=f(nombre,varargin)      f=str2func(nombre)      a=f(varargin{1:end});    end   function d=overpower(j,c)       d=j*c;    end    function e=poweroverwelming(j)      e=j;   end 

function placement

matlab, unlike number of other languages, permits single file contain 1 main function visible rest of system. main function first function. (documentation)

any functions defined after main function body called local functions. these functions each create own separate workspace (scope) , can called 1 and, of course, main function.

any functions defined within main function body called nested functions. these functions have own workspace able access , change variables of parent function under conditions. nested functions @ same nesting level can call each other , local functions, local functions cannot call nested functions since out of scope.

workarounds

there several options available depending on how proceed. @ risk of giving many options desiring exhaustive, i'll put list first last. things, recommend 1 or 2. other options more creating libraries/apis, included them show can done.

1. define function1 , function2 in separate m-files on matlab path or in present working directory call them normally.

2. wrap main body of work (the 1 calling functions) in function , define other functions local functions or nested functions. example:

function output = main(a,b,c)   result=function1(a,b,c);    result2=function2(b,d);   ...    % can define function1 , function2 here nested functions end   % or can define function1 , function2 here local functions 

3. you can bit more fancy , have function returns function handles (pointers) local or nested functions , use (in example) struct call functions in script:

function functions = getfunctions()   functions.f1 = @(a,b,c) function1(a,b,c);    functions.f2 = @(a,b)   function2(a,b);     % can define function1 , function2 here nested functions end   % or can define function1 , function2 here local functions 

4. if have r2013b or above, can same thing above using localfunctions function create cell array of handles local functions (in case, definitions required outside main function body).

function functions = getfunctions()   functions = localfunctions(); % r2013b+ end   % define function1 , function2 here local functions 

5. you can create class static functions:

classdef functions   methods(static)     % define function1 , function2 here , call them struct above.   end end 

i hope makes sense , helps.
