Save in nested loop

Question

0 个投票

Hi,

I'm a bit lost concerning saving data in loops. I have a list of data that I need to analyse with several parameters.

 list_files2load = dir('*.txt');
 files = {list_files2load.name};
 m = length(files);
 for w=1:m
 sprintf('loading file : %s', files{w})
 s = load(files{w});
    for A:1:2:20
    ...
     for n=1:17
       if... <B
       if... <A
         plot....
         saveas(gcf,[files{w}-A-n], 'ai')
       end
       end
     ...
     save('files{w}-A-n', 'data', 'ASCII')
     end
  end

my problem is that I would like to save the data inside the loop, something like data-1-1, then data-1-2 and so on until data-20-17, but i have no clues...

I'll appreciate any help!

cheers

n.

See FAQ: dynamically generate file name, FAQ: Process sequence of files

for A:1:2:20
  for n=1:17
     Name = sprintf('%s-%d-%d', files{w}, A, n);
     saveas(gcf, Name, 'ai')
     save(Name, 'data', 'ASCII')
  end

File = 'data.txt'

[FilePath, FileName, FileExt] = fileparts(File)

It is always a reliable method to use absolute file names including the path. See also: help fullfile.
