It seems that you're encountering an issue with downloading the dataset files using the matlab.internal.examples.downloadSupportFile function. This error might be due to a variety of reasons, including but bot limited to network issues.
If the automatic download is failing, you can manually download the files and place them in a folder of your choice (preferably anywhere except the temp directory, as writing permissions for MATLAB may have been disabled).
Here's the snippet you can use (replace tdir with a directory of your choice):
if trainNetworkFlag
% Manually download the training data set
trainingDatasetZipFile = fullfile(tdir, 'fetal-ecg-source-separation-trainingData.zip');
websave(trainingDatasetZipFile, 'https://ssd.mathworks.com/supportfiles/SPT/data/fetal-ecg-source-separation-trainingData.zip');
trainingDatasetFolder = fullfile(tdir, 'fetal-ecg-source-separation-trainingData');
if ~exist(trainingDatasetFolder, 'dir')
unzip(trainingDatasetZipFile, trainingDatasetFolder);
end
end
% Manually download the test data set
testDatasetZipFile = fullfile(tdir, 'fetal-ecg-source-separation-testData.zip');
websave(testDatasetZipFile, 'https://ssd.mathworks.com/supportfiles/SPT/data/fetal-ecg-source-separation-testData.zip');
testDatasetFolder = fullfile(tdir, 'fetal-ecg-source-separation-testData');
if ~exist(testDatasetFolder, 'dir')
unzip(testDatasetZipFile, testDatasetFolder);
end
As an ending note, please ensure you are using MATLAB release R2022b or later.
Hope it helps!
