Dear all,
This is the answer of my professor about the ECG detection, but I cant run that code. Anyone know how to fix this, please help me
clc;
close all;
clear all;
load ecg_sbj1
load ecg_sbj2
load ecg_sbj3
load ecg_sbj4
nms = getMemberNames(heartrates);
for k = 1:heartrates.NumMembers
v = getLabelValues(heartrates,k,["QRSregions" "Rpeaks"]);
hr = diff(cellfun(@(x) x.Location,v));
subplot(2,1,k)
histogram(hr,0.5:0.025:1.5)
legend("hrv = " + std(hr))
ylabel(nms(k))
ylim([0 6])
end
function [labelVals,labelLocs] = findQRS(x,t,parentLabelVal,parentLabelLoc,varargin)
labelVals = cell(2,1);
labelLocs = cell(2,1);
if nargin<5
Fs = 250;
else
Fs = varargin{1};
end
df = 20;
load("trainedQTSegmentationNetwork","net")
for kj = 1:size(x,2)
sig = x(:,kj);
mitFSST = computeFSST(sig,Fs);
netPreds = classify(net,mitFSST,MiniBatchSize==50);
QRS = categorical([netPreds{1} netPreds{2}]',"QRS");
msk = signalMask(QRS,MinLength==df,SampleRate==Fs);
r = roimask(msk);
labelVals{kj} = r.Value;
labelLocs{kj} = r.ROILimits;
end
labelVals = vertcat(labelVals{:});
labelLocs = cell2mat(labelLocs);
end

You need the Signal Processing Toolbox in order to use getMemberNames. If it is included on your license, you can use theAdd-ons Explorer to add it.
However, once added, you will find that you do not have a variable names heartrates.

I cannot create the variable for you. You must have code somewhere that does that already.
Each mat file of yours contains 2 variables - ecg and Fs. By loading them back to back the way you are doing, you will only be able to access the data in ecg_sbj4, as it overwrites all the others.
You may need to go back to your professor for more details.
