Hello,
I have a matlab script that processes some data for each hour of the day and saves each result as > " result_ddmmyy_hh.mat " file.
This gives me a file of all the resultant data processed for that hour.
I use this script on a loop to study the data for the whole day and then the same for the whole week.
Now I have too many files (24 X 7). I would like to store all the results of each day as one complete file, that way i will have only 7 meta-data files.
Is there a way to do this directly without re-running the entire script? Can I directly merge multiple .mat files into one .mat file?
Thank you in advance!
David :)

You can load all 24 .mat files for a single day and then save all of the collected variables together as one .mat file. For example:
Collected = cell(24,1);
for Hour=1:24
fname = ['FileForHour' num2str(Hour) '.mat'];
Collected{Hour} = load(fname);
end
save('CollectedForThisDay','Collected')
Details might change a bit depending on how the hourly variables are named and how you want them named in the collected file.

This works!!
I had to adjust some of my data, but the idea is fantastic.
Thank you! :)
