How to solve the error as the existing image file is in jpg type?

Or is there any alternative method to prepare dataset for machine learning

There are a number of different problems with what you have done.

But I recommend that instead of trying to fix it, that you instead use an imageDatastore https://www.mathworks.com/help/matlab/ref/matlab.io.datastore.imagedatastore.html . Many of the Deep Learning algorithms already know how to handle those.

在 MATLAB Online 中打开

From my understanding you want to import multiple images into MATLAB. Here is a code which might help you:

% Read in all images from a folder called 'images'
imgFolder = fullfile('images');
imgs = imageDatastore(imgFolder);
numOfImgs = length(imgs.Files);
for ii = 1:numOfImgs
    % do operation on the images as your requirement 
end
