I wish to import all the image into a .mat file for machine learning.

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.

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 

You can refer imageDatastore for more information.
