この関数はmファイルにあり、プッシュボタンのコールバックを作成したいのですが、方法がわかりません。誰か助けてもらえますか?これは機能です:

function f=fftreal(f,N,dim);
error(nargchk(1,3,nargin));

if nargin<3
  dim=[];  
end;

if nargin<2
  N=[];
end;

if ~isreal(f)
  error('Input signal must be real.');
end;


[f,N,Ls,W,dim,permutedsize,order]=assert_sigreshape_pre(f,N,dim,'FFTREAL');

N2=floor(N/2)+1;

f=comp_fftreal(f);

permutedsize(1)=N2;

f=assert_sigreshape_post(f,dim,permutedsize,order);
end

これは、GUIが自動的に生成したユーザーインターフェイスコードです。

function varargout = Fourier_Transform_GUI(varargin)
%FOURIER_TRANSFORM_GUI M-file for Fourier_Transform_GUI.fig
%      FOURIER_TRANSFORM_GUI, by itself, creates a new FOURIER_TRANSFORM_GUI or raises the existing
%      singleton*.
%
%      H = FOURIER_TRANSFORM_GUI returns the handle to a new FOURIER_TRANSFORM_GUI or the handle to
%      the existing singleton*.
%
%      FOURIER_TRANSFORM_GUI('Property','Value',...) creates a new FOURIER_TRANSFORM_GUI using the
%      given property value pairs. Unrecognized properties are passed via
%      varargin to Fourier_Transform_GUI_OpeningFcn.  This calling syntax produces a
%      warning when there is an existing singleton*.
%
%      FOURIER_TRANSFORM_GUI('CALLBACK') and FOURIER_TRANSFORM_GUI('CALLBACK',hObject,...) call the
%      local function named CALLBACK in FOURIER_TRANSFORM_GUI.M with the given input
%      arguments.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".

%pre-processing
f=fftreal(f,N,dim);
% post-processing

これは、FFT ボタンを押した後に実行されるコードの一部です...

したがって、ここで独自の関数を呼び出すと、完了です。
