当我运行此代码时,它只给了我以下错误
matlab.graphics.internal.figfile.FigFile /读取> @(hObject,EVENTDATA)名字(' pushbutton2_Callback',hObject,EVENTDATA,guidata(hObject)) 评估UIControl回调时出错
这是我的代码
function varargout = untitled(varargin)
% UNTITLED MATLAB code for untitled.fig
% UNTITLED, by itself, creates a new UNTITLED or raises the existing
% singleton*.
%
% H = UNTITLED returns the handle to a new UNTITLED or the handle to
% the existing singleton*.
%
% UNTITLED('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in UNTITLED.M with the given input arguments.
%
% UNTITLED('Property','Value',...) creates a new UNTITLED or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before untitled_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to untitled_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".

有什么建议,谢谢。
答案 0 :(得分:0)
您没有将speech
保存到handles
结构中。您需要使用guidata
function bushbutton1_Callback(hobject,eventdata,handles)
x = audiorecorder(16000,16,1);
recordblocking(x,3);
handles.speech = getaudiodata(x,'double');
% Save the updated handles struct
guidata(hobject, handles);
end
function pushbutton2_Callback(hObject, eventdata, handles)
axes(handles.axes1)
plot(handles.speech)
end
或仅使用speech
,因为您已将其定义为全局变量。请注意,这不太可取,因为使用global
变量可能会导致许多问题。
function pushbutton2_Callback(hObject, eventdata, handles)
gloabl speech
plot(speech)
end
