Do NOT store user files in the installation directory of any application!
'C:\Program Files\MATLAB\R2022b\bin\my_excel_file.xls' % !!! DO NOT use this location !!!
Your Windows should protect the installation folder, so whatever you are doing ... is best avoided.

Two things:
1) You're using
y1 = xlsread('F:\matlab\bin_my_excel_file');
% ^ underscore
but 'bin' is a directory and the file is (supposedly) 'my_excel_file', so that should be
y = xlsread('F:\matlab\bin\my_excel_file');
% ^ backslash
2) Specify the file name completely, including the extension, either .csv or .xls. I don't know which one you mean because they both exist.
% which file?
% this one:
y1 = xlsread('F:\matlab\bin\my_excel_file.csv')
% or this one:
y1 = xlsread('F:\matlab\bin\my_excel_file.xls')
Also, readmatrix, readtable, and readcell are recommended over xlsread in R2022b.
You can pick the one that makes the most sense for the class of the variable that should represent the contents of the file (a matrix, a table, or a cell array, respectively).

We recommend against storing files in the MATLAB execution directory. You would need to be running with elevated access rights in order to be permtited to write files there.

@Md. Mohidul Islam: Do you have another question about the code you posted? If you want someone to be able to run it, they'd need to have the required files, including:
C:\Program Files\MATLAB\R2022b\bin\my_excel_file.xls
I:\BIOM_Signal_processing\Hw5\ECGsignal_1.mat
I:\BIOM_Signal_processing\Hw5\ECGsignal_1.xls
