Index exceeds the number of array elements

fullFileName = fullfile(dicomFolder, dicomFiles(2).name);

dicomInfo = dicominfo(fullFileName);

grayImage = dicomread(dicomInfo);

fullFileName = fullfile(jpegFolder, jpegFiles(363).name);

grayImageJpeg = 255*imread(fullFileName);

When I change the dicom file number or jpeg file number, I got always index exceeds the number of array elements error. Index must not exceed 0 but I don't know how to solve this problem.

The error would suggest that dicomFiles and jpegFiles are empty.

You haven't shared the code that creates those variables, so we can't offer much help other than to say that when they are created, they are not assigned any values.

A = [];
A(1)

Index exceeds the number of array elements. Index must not exceed 0.
