Trying to save a Matlab file with a timestamp

Hello, I am writing up a code that is producing a basic projectile motion graph. I want each graph to be saved to a folder on my desktop where each file is saved under a timestamp from when it was created. I am new and not sure if this is too challenging. Can anyone help or offer suggestions. Thanks

for i = 1:10
    data = rand(100,1) ; 
    fname = strcat('projjectile',string(datetime('now','Format',"yyyy-MM-dd-HH-mm-ss")),'.mat') ;
    save(fname,'data')
end

For clarity and efficiency (no superfluous type conversions), prefer sprintf over string concatenation:

sprintf('projjectile_%s.mat',datetime('now','Format',"yyyy-MM-dd-HH-mm-ss"))

ans = 'projjectile_2021-04-09-03-53-22.mat'
