向GUI提供輸入並捕獲輸出以便在另一個功能中使用它

Question

我已經創建了一個GUI函數，如下所示。我想要做的是將這個GUI放在一個循環中，以便我可以將它用於不同的元素。對於輸出我有兩個向量是6乘1.我想要做的是，當我選擇不同的單選按鈕，並在GUI的編輯文本中放置不同的值，將結果保存在輸出的不同位置矢量取決於單選按鈕。我試圖給GUI一個標題作爲輸入。

在此先感謝。

function varargout = distributedloads(varargin) 
% DISTRIBUTEDLOADS MATLAB code for distributedloads.fig 
%  DISTRIBUTEDLOADS, by itself, creates a new DISTRIBUTEDLOADS or raises the existing 
%  singleton*. 
% 
%  H = DISTRIBUTEDLOADS returns the handle to a new DISTRIBUTEDLOADS or the handle to 
%  the existing singleton*. 
% 
%  DISTRIBUTEDLOADS('CALLBACK',hObject,eventData,handles,...) calls the local 
%  function named CALLBACK in DISTRIBUTEDLOADS.M with the given input arguments. 
% 
%  DISTRIBUTEDLOADS('Property','Value',...) creates a new DISTRIBUTEDLOADS or raises the 
%  existing singleton*. Starting from the left, property value pairs are 
%  applied to the GUI before distributedloads_OpeningFcn gets called. An 
%  unrecognized property name or invalid value makes property application 
%  stop. All inputs are passed to distributedloads_OpeningFcn via varargin. 
% 
%  *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one 
%  instance to run (singleton)".

我寫了一個創建GUI和一個回調函數的示例腳本。

在GUI中有向量單選按鈕，按鈕和帶有線條的可視化結果的軸。

腳本代碼：

close all   % close all figures 
figure    % open a figure for GUI 
Values=zeros(3,1); % Variable of the interest 

UIGroup=uibuttongroup('parent',gcf,'position',[0 0 1 1]); % Group for Radio Buttons 
for ii=1:3   % create 3 Radio buttons, for example 
    RB(ii)=uicontrol('style','radiobutton',... 
        'units','normalized','position',[.05, ii/10 0.15 0.1],... 
        'parent',UIGroup,'string',['Button ' num2str(ii)]); 
end 
% Push Button that runs DoIt function 
uicontrol('style','pushbutton','string','DO',... 
      'units','normalized','position',[0.45 0.05 0.1 0.1],... 
      'callback','Values=DoIt(RB,L,Values);') 

% Axes and Line just for example 
ax=axes('units','normalized','position',[0.25 0.2 0.6 0.7],... 
     'xlim',[-0.1 3.1],'ylim',[-0.1 1.1]); 
L=line('xdata',1:3,'ydata',Values,'marker','.','linestyle','none') 

此腳本定義Values變量和GUI的內容。
按鈕運行DoIt函數，該函數根據RB句柄將新內容分配給Values。 Values僅用於保存Values中的其他值，L僅用於可視化更改。

度特代碼：

function[OutValues]=DoIt(RadioHandle,LineHandle,InValues) 
    OutValues=InValues;  % Copy Values from input to output variable 
%% Find which radio button is active 
    M=max(size(RadioHandle)); 
    for ii=1:M 
     Radios(ii)=get(RadioHandle(ii),'value'); 
    end 
    RadioChecked=find(Radios==1);  % This RadioButton is active 

    OutValues(RadioChecked)=ProcessIt;  % Process the chosen position. 
    set(LineHandle,'ydata',OutValues);% Visualize the change 

function[OUT]=ProcessIt() 
    OUT=rand; % this function will just return random value, for example. 

的DoIt函數讀取處理，以單選按鈕RB並確定哪個按鈕是激活的。然後，它將更改Value變量中的適當值並返回並根據句柄L更改y值。

在這個例子中，它將隨機值賦值給定義的點，但是您可以從工作區/父函數傳遞任何變量並調用任何函數。
