matlab iterative filenames for saving

Question

this question about matlab: i\'m running a loop and each iteration a new set of data is produced, and I want it to be saved in a new file each time. I also overwrite old fi

Answer 1

You could also generate all file names in advance using NUM2STR:

>> filenames = cellstr(num2str((1:10)','string_new.%02d.mat'))

filenames = 
    'string_new.01.mat'
    'string_new.02.mat'
    'string_new.03.mat'
    'string_new.04.mat'
    'string_new.05.mat'
    'string_new.06.mat'
    'string_new.07.mat'
    'string_new.08.mat'
    'string_new.09.mat'
    'string_new.10.mat'

Now access the cell array contents as filenames{i} in each iteration
