I have made a function (having name preprocessing) and calling it by following command in Command Window.
preprocessing('C:\Users\Explorer\Documents\MATLAB\PhysioNet_Database\Malignant_Ventricular_Ectopy_Database\418m.mat')
But getting Error and here it is:
Error using upfirdn>validateinput (line 102)
The input signal X must be a double-precision vector.
Error in upfirdn (line 82)
[p,q] = validateinput(x,h,varargin);
Error in resample (line 119)
y = upfirdn(x,h,p,q);
Error in preprocessing (line 21)
r_nsr16265=resample(nsr16265,256,fs); % Resampling
By the way, if it asks for default sampling frequency, enter 250.

Well that's a broken website. :(
I have downloaded and attached the file so that no-one else needs to go through that... experience .

That routine does not accept file names.
filestruct = load('C:\Users\Explorer\Documents\MATLAB\PhysioNet_Database\Malignant_Ventricular_Ectopy_Database\418m.mat');
preprocessing(filestruct.x)

I got the answer in your last comment here i.e You need to load the .mat file and access the appropriate variable from the file
I just replaced line # 18 of function by this
nsr16265=x.val(1,:);
Thank you!
