function varargout = attendancetable_1(varargin)
% ATTENDANCETABLE_1 MATLAB code for attendancetable_1.fig
% ATTENDANCETABLE_1, by itself, creates a new ATTENDANCETABLE_1 or raises the existing
% singleton*.
%
% H = ATTENDANCETABLE_1 returns the handle to a new ATTENDANCETABLE_1 or the handle to
% the existing singleton*.
%
% ATTENDANCETABLE_1('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in ATTENDANCETABLE_1.M with the given input arguments.
%
% ATTENDANCETABLE_1('Property','Value',...) creates a new ATTENDANCETABLE_1 or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before attendancetable_1_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to attendancetable_1_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".

To use "xlswrite" your data must be of type specified in the error description. When you use "p.MyData" to store your data, variable "p" becomes a structure.
To store this data you should use
xlswrite(filename,p.MyData)
Also, using an empty array to initialize your data might throw an error if the input array for xlswrite remains empty. A workaround to this could be to initialize "p.MyData" as
p.MyData = [NaN];
This would create an empty excel sheet as MATLAB will convert NaN to empty cell. You can find more information here.
Note: If you are using MATLAB R2019a or later, it is recommended that you use writetable, writematrix, or writecell instead of xlswrite.
