How to create a function within a function ?

i have two scripts with a function on each but i need the two functions to run on one script. My two functions are as follows:

function f = OscillationsofStr( x )

% Input:
% x = the co-ordinate of the point 
% Data 

% Output:  
% f=x*sin(x)+cos(x)  

f=x*sin(x)+cos(x);

end

function alpha=solEquation() 

% Data 
alphaIni=0; 
alphaEnd=4; 

% The oscillations of the Structure function 

alpha=fzero(@OscillationsofStr,[alphaIni,alphaEnd],1);

If you want them to reside in one file, you need to switch the order, so that the calling (main) function is before the called (local) function.

See also Local Functions

function alpha=solEquation()

% Data 
alphaIni=0; alphaEnd=4;

% The oscillations of the Structure function

alpha=fzero(@OscillationsofStr,[alphaIni,alphaEnd],1);

end

function f = OscillationsofStr( x )

% Input: % x = the co-ordinate of the point % Data

% Output: % f=x*sin(x)+cos(x)

f=x*sin(x)+cos(x);

end

Thank you very much you hero :)
