MATLAB: How to convert matrix to CSV file

Question

Hello.

I want to convert matrix to CSV file.

When I used this code, I got this result.

I want to convert sequences{i} to each CSV file. Could you explain how to make eack CSV file using for loop?

netCNN = googlenet;
dataFolder = "hmdb51_org";
[files,labels] = hmdb51Files(dataFolder);
idx = 1;
filename = files(idx);
video = readVideo(filename);
size(video)
labels(idx)
numFrames = size(video,4);
figure
for i = 1:numFrames
    frame = video(:,:,:,i);
    imshow(frame/255);
    drawnow
end
inputSize = netCNN.Layers(1).InputSize(1:2);
layerName = "pool5-7x7_s1";
tempFile = fullfile(tempdir,"hmdb51_org.mat");
if exist(tempFile,'file')
    load(tempFile,"sequences")
else
    numFiles = numel(files);
    sequences = cell(numFiles,1);
    
    for i = 1:numFiles
        fprintf("Reading file %d of %d...\n", i, numFiles)
        
        video = readVideo(files(i));
        video = centerCrop(video,inputSize);
        
        sequences{i,1} = activations(netCNN,video,layerName,'OutputAs','columns');
        
    end
    
    save(tempFile,"sequences","-v7.3");
end
csvwrite('hmdb51_org/bend1.csv', sequences{1});
csvwrite('hmdb51_org/bend2.csv', sequences{2});
csvwrite('hmdb51_org/bend3.csv', sequences{3});

Answer 1

for i = 1:length(sequences)
    csvwrite(['hmdb51_org/bend',num2str(i),'.csv'], sequences{i});
end
