我正在为 Matlab gui 界面的工作方式而苦苦挣扎。

我不是在寻找答案，只是在寻找更多关于如何做到这一点的指导。

我正在尝试将编辑框中的温度从 F 转换为 C ...所以我认为我需要将方程式放在按钮中。

我想我被困在如何将数字从编辑框传递到按钮以进行转换，然后如何将其传回，然后显示它。这有道理吗？

function varargout = ICA09A_TEMPFtoC(varargin)
% ICA09A_TEMPFTOC MATLAB code for ICA09A_TEMPFtoC.fig
%      ICA09A_TEMPFTOC, by itself, creates a new ICA09A_TEMPFTOC or raises the existing
%      singleton*.
%
%      H = ICA09A_TEMPFTOC returns the handle to a new ICA09A_TEMPFTOC or the handle to
%      the existing singleton*.
%
%      ICA09A_TEMPFTOC('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in ICA09A_TEMPFTOC.M with the given input arguments.
%
%      ICA09A_TEMPFTOC('Property','Value',...) creates a new ICA09A_TEMPFTOC or raises     the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before ICA09A_TEMPFtoC_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to ICA09A_TEMPFtoC_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".

% --- Executes just before ICA09A_TEMPFtoC is made visible.
function ICA09A_TEMPFtoC_OpeningFcn(hObject, eventdata, handles, varargin)
% This function has no output args, see OutputFcn.
% hObject    handle to figure
% eventdata  reserved - to be defined in a future version of MATLAB

Result = (5 / 9) * (InputNumber - 32);

set(handles.result, 'Convert', Result);

%        str2double(get(hObject,'String')) returns contents of degF_et as a double
UserInput = str2double(get(hObject,'String'))

% --- Executes during object creation, after setting all properties.
function degF_et_CreateFcn(hObject, eventdata, handles)
% hObject    handle to degF_et (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    empty - handles not created until after all CreateFcns called

% Hint: edit controls usually have a white background on Windows.

    if ispc && isequal(get(hObject,'BackgroundColor'),          get(0,'defaultUicontrolBackgroundColor'))

end

我应该做些什么来使任何编辑的人都更具可读性？

要获取在文本编辑框中输入的温度，请使用：

tempF = get(handles.degF_et,'String');

这可以从按钮功能中调用。

要更改那里显示的字符串，请使用：

set(handles.degF_et,'String','some string');
