[old_path]=which('rdsamp'); if(~isempty(old_path)) rmpath(old_path(1:end-8)); end
wfdb_url='https://physionet.org/physiotools/matlab/wfdb-app-matlab/wfdb-app-toolbox-0-10-0.zip';
[filestr,status] = urlwrite(wfdb_url,'wfdb-app-toolbox-0-10-0.zip');

That is exactly the same code I posted more than 5 years ago at https://www.mathworks.com/matlabcentral/answers/599659-how-to-install-wfdb-toolbox-in-matlab#answer_500806

Create a new folder in any convenient location that you have write access to, and which is not underneath the Windows program installation directory (in particular, somewhere that is not inside the MATLAB installation directory.)

The name you use for the folder is not important, but you should probably avoid having spaces or non-ASCII characters in the name.

Go into MATLAB.

Inside MATLAB, Use cd to change directories, naming the folder you created above.

Now run the code listed at https://archive.physionet.org/physiotools/matlab/wfdb-app-matlab/ which is

[old_path]=which('rdsamp'); if(~isempty(old_path)) rmpath(old_path(1:end-8)); end
wfdb_url='https://physionet.org/physiotools/matlab/wfdb-app-matlab/wfdb-app-toolbox-0-10-0.zip';
[filestr,status] = urlwrite(wfdb_url,'wfdb-app-toolbox-0-10-0.zip');
unzip('wfdb-app-toolbox-0-10-0.zip');
cd mcode
addpath(pwd)
savepath

You can copy the code from here and paste it into your MATLAB command Window.

The program will install itself.

Afterwards, you can call upon the functions of the toolbox from any of your programs. You do not need to be cd'd to the directory that contains the toolbox.

thank u so much for help....but there is show a warning

[SUDESHNA]

First of all i was also facing the same problem.

later on i downladed the zip file from this site, https://physionet.org/content/wfdb-matlab/0.10.0/ saved it in my downloads then created a new folder somewhere else in E drive.

then i tried the the code listed at https://archive.physionet.org/physiotools/matlab/wfdb-app-matlab/

And it worked. Though it has many warnings still the demo worked ... showed 3 figs after demo finished.

hope it helps.

@SUDESHNA

The code is warning you because you used a directory named MY WORK & PUBLICATIONS which contains spaces in it. The code warns because the code potentially has problems running from a directory name that contains spaces.

You should ideally rename your directory, perhaps to something like MY_WORK&PUBLICATIONS
