Thank you.

Use dir to get the names of the files and then use a for loop to process the files.

Thanks for the answer.

I managed to read the directory, but could not mount the loop. Can you help me again? The files have the following name:

"hmi.m_45s.001_TAI.magnetogram.fits.dat" with variations "002", "003", .... until "296".

How can I mount the loop for this structure? I'm struggling because the file names are not just numbers. = /

I thank you again.

d = dir('*TAI.magnetogram.fits.dat')
for i = 1:numel(d)
  filename = d(i).name
  % read filename and process data
end
