Hello everyone, I got this error and I do not know how to solve. Could you help me finding the problem in the following code please?

function varargout = Bai1(varargin)
% BAI1 MATLAB code for Bai1.fig
% BAI1, by itself, creates a new BAI1 or raises the existing
% singleton*.
%
% H = BAI1 returns the handle to a new BAI1 or the handle to
% the existing singleton*.
%
% BAI1('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in BAI1.M with the given input arguments.
%
% BAI1('Property','Value',...) creates a new BAI1 or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before Bai1_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to Bai1_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".

% See also: GUIDE, GUIDATA, GUIHANDLES

We will probably need the .fig file to debug this.

[Hoàng Duy]

Thanks for your help

[Hoàng Duy]

Can u help me :(

[Walter Roberson]

I had a hard drive crash a few days ago. I had copied all my matlab code to a different drive before that, but I just discovered that the m files are all empty!! So I will need some time to investigate.

[Walter Roberson]

This is the wrong .fig file by the way. The .fig file must be named the same thing as the .m file or else MATLAB will not be able to locate the .fig . The function is named Bai1 so we need to see Bai1.fig

[Hoàng Duy]

Thank you, I had change name to bai1.fig
