评论： Walter Roberson 2022-10-5

When I run the below .m file, it gives me the following error:

Error using feval
Undefined function 'frequency_axes_CreateFcn' for input arguments of type 'matlab.graphics.axis.Axes'.
Error in gui_mainfcn (line 95)
        feval(varargin{:});
Error in TestInterface (line 43)
    gui_mainfcn(gui_State, varargin{:});
Error in @(hObject,eventdata)TestInterface('frequency_axes_CreateFcn',hObject,eventdata,guidata(hObject))

Any idea why? Here's the code from my .m:

function varargout = TestInterface(varargin)
% TESTINTERFACE Application M-file for TestInterface.fig
%   TESTINTERFACE, by itself, creates a new TESTINTERFACE or raises the existing
%   singleton*.
%
%   H = TESTINTERFACE returns the handle to a new TESTINTERFACE or the handle to
%   the existing singleton*.
%
%   TESTINTERFACE('CALLBACK',hObject,eventData,handles,...) calls the local
%   function named CALLBACK in TESTINTERFACE.M with the given input arguments.
%
%   TESTINTERFACE('Property','Value',...) creates a new TESTINTERFACE or raises the
%   existing singleton*.  Starting from the left, property value pairs are
%   applied to the GUI before two_axes_OpeningFunction gets called.  An
%   unrecognized property name or invalid value makes property application
%   stop.  All inputs are passed to TestInterface_OpeningFcn via varargin.

%   *See GUI Options - GUI allows only one instance to run (singleton).

You probably copied a GUIDE-created .fig and edited it, instead of opening the interface in GUIDE and telling GUIDE to save it under a new name. Or perhaps you deleted an axes named frequency_axes without going through GUIDE to do so.

Are you launching the interface by double-clicking on the .fig or by commanding

TestInterface

on the command line? Double-clicking would invoke a callback saved with the .fig and it is that callback,

@(hObject,eventdata)TestInterface( 'frequency_axes_CreateFcn', hObject,eventdata,guidata(hObject))

that is causing the problem.

The quick fix is adding a function to your file,

function frequency_axes_Createfcn(varargin)

that does nothing.

The longer term fix is to use the figure browser to find that callback and delete it. Or you can use findobj() or findall() to retrieve the figure properties, look at the callback functions, find the errant one and overwrite it, and re-save the .fig.

You are trying to pass a frame number into VideoReader(). VideoReader() is not the correct routine to read in a particular frame. You should change your code from

for i=1:frm_cnt
    frm(i)=VideoReader(filename,i);         % read the Video file
    frm_name=frame2im(frm(i));      % Convert Frame to image file
    filename1=strcat(strcat(num2str(i)),str2);
    imwrite(frm_name,filename1);      % Write image file  
     waitbar(i/frm_cnt,h)
end

to instead be

vid = VideoReader(filename);
for i=1:frm_cnt
    frm_name=readFrame(vid);         % read the Video file
    filename1=strcat(strcat(num2str(i)),str2);
    imwrite(frm_name,filename1);      % Write image file  
     waitbar(i/frm_cnt,h)
end
clear vid

However, I warn you that the frame count returned by aviinfo is usually incorrect if the video is Variable Frame Rate (which most videos are these days.) You would be better off ignoring what aviinfo tells you are the number of frames, and instead use

vid = VideoReader(filename);
i = 0;
while hasFrame(vid)
    frm_name=readFrame(vid);         % read the Video file
    i = i + 1;
    filename1=strcat(strcat(num2str(i)),str2);
    imwrite(frm_name,filename1);      % Write image file  
     waitbar(i/frm_cnt,h)
end
clear vid

Do you have pushbutton1_Callback invoking sim()? If you are, then you are invoking a Simulink model that relies on some values being present in the workspace of the function that calls sim(). Those might be defined as parameters or there might be From Workspace blocks.

The simulation needs

b
r
th_in
Xs

Your code does not define anything like b. Your code defines R with a capital R, but not lower-case r. Your code does not define anything like th_in. Your code defines Sx but not Xs

At the moment, I am not certain what is going on for WMR_Project_sim_2013GUI/Constant4 -- perhaps you left the definition of the constant empty in Simulink ?

That code does not contain a guidata call.

You need to replace the first ~ of the function definition of that callback with hObject

Your cell array for uigetfile has one column in the first row but 2 columns in the other rows.

I have the same problem and only thing I've learned after browsing for so long is that the cause is the same in most cases, but no singular solution as far as I can tell. I've been searching the web for days trying to fix it to no avail.

The 'myecg' variable is an imported one that I had ready. I tried renaming it but that didn't work either.

Undefined function or variable 'myecg'.
Error in CEN320Project>pushbutton1_Callback (line 81)

Now it says undefined variable 'N' even though I did define it as the value inside the editbox using the "str2double" command.

and the feval varargin error still shows up .

If it's not too much trouble. This is my entire program, It's fairly simple I think.

function varargout = CEN320Project(varargin)
% CEN320PROJECT MATLAB code for CEN320Project.fig
%      CEN320PROJECT, by itself, creates a new CEN320PROJECT or raises the existing
%      singleton*.

%      the existing singleton*.
%
%      CEN320PROJECT('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in CEN320PROJECT.M with the given input arguments.
%
%      CEN320PROJECT('Property','Value',...) creates a new CEN320PROJECT or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before CEN320Project_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to CEN320Project_OpeningFcn via varargin.

We are helping you. Ask a separate question after reading what Image Analyst linked you. You should also consider doing the Onramp tutorial, which is offered for free by Mathworks.

Walter Roberson 2022-10-5

using clear all in the middle of the program is like yanking out the chair you are standing on... together with the floor the chair is on, and the building that the floor is in, and the hill that the building is on, and the planet that the hill is on... and the sun that the planet orbits, and the local cluster that the sun is part of... and the galaxy that the local cluster is part of... and then hoping that the residual vacuum energy will still hold you up.

Either you do not have the Image Processing Toolbox installed (or licensed), or else you are using a MATLAB release before R2016a. I suspect you are using a MATLAB too old for imoverlay()

it is giving error at handles part, the following is the result I got with breakpoint at that function.

28  gui_Singleton = 1;
K>> dbcont
166 T = Robot.fkine([Th_1 Th_2 Th_3]);
K>> dbcont
Index in position 2 exceeds array bounds (must not exceed 1).
Error in RRR_Robot>btn_Forward_Callback (line 167)
handles.Pos_X.String = num2str(floor(T(1,4)));

Put a breakpoint at

T = Robot.fkine([Th_1 Th_2 Th_3]);

and single-step by typing dbstep ( not dbcont) . If you then ask to display T, what shows up?

%      EITAPP, by itself, creates a new EITAPP or raises the existing
%      singleton*.

%      H = EITAPP returns the handle to a new EITAPP or the handle to
%      the existing singleton*.
%
%      EITAPP('CALLBACK',hObject,eventData,handles,...) calls the local

Hi there,

I am currently facing the same issue here. Would be glad if you could assist me. I have tried the same method you issued to the first question and it gave me this.

Thank you

when i run my .m file, i got error

Undefined function 'fitcknn' for input arguments

this is i run dbstop if error , and the result

svmtrain() requires Statistics Toolbox, R2013a to R2017b.

For newer releases it has been replaced with https://www.mathworks.com/help/releases/R2017a/stats/fitcsvm.html

% Check that user has the specified Toolbox installed and licensed.
% hasLicenseForToolbox = license('test', 'image_toolbox');	% Check for Image Processing Toolbox.
% hasLicenseForToolbox = license('test', 'Image_Acquisition_Toolbox');	% Check for Image Acquisition Toolbox.
hasLicenseForToolbox = license('test', 'Statistics_Toolbox');	% Check for Statistics and Machine Learning Toolbox.
% hasLicenseForToolbox = license('test', 'Signal_Toolbox');	% Check for Signal Processing Toolbox.
% hasLicenseForToolbox = license('test', 'Video_and_Image_Blockset');	% Check for Computer Vision System Toolbox.
% hasLicenseForToolbox = license('test', 'Neural_Network_Toolbox');	% Check for Deep Learning Toolbox.
