从外部功能到Matlab中的GUI轴的图

Question

我需要在通过轴创建的GUI中显示我创建的“ LinearOpticalElement.m”文件的功能。我应该怎么做？

我已经实现了一些情况，以防以后需要添加更多功能。我该怎么办？

我在GUI函数调用另一个函数LinearOpticalElementsGUI.m时遇到麻烦

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

Answer 1

问题似乎在于，“ LinearOpticalElementsGUI”是脚本而不是函数。脚本没有返回值。因此，您可以尝试简单地调用脚本，而不是将不存在的返回值传递给函数。

% --- Executes on button press in pushbutton1.
function pushbutton1_Callback(hObject, eventdata, handles)
% hObject    handle to pushbutton1 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
axes(handles.axes1);
cla;

popup_sel_index = get(handles.popupmenu1, 'Value');
switch popup_sel_index
    case 1

        LinearOpticalElementsGUI;


end

这可能显示一个新轴。因此，您也可以尝试在脚本中调用以下绘图函数：plot(gca(), xaxx, ...)

---

但是实际上，将脚本“ LinearOpticalElementsGUI”转换为以轴句柄作为参数的函数将是更好的样式。

function LinearOpticalElementsGUI(ax)

% "clc" and "clear" not useful
% ...
% "figure(...)" is not needed anymore
% ...

   plot(ax, xaxx, ...)

% ...
end
