I have this code

C = cell(1, 10);
for m = 1:10
C{m} = load(sprintf('tot__r1_%03d.dat', m));
A=zeros(256);
B=C{1,m}
A(B(:,1))=B(:,2);
%here I need code that does Y(m)=A
end

I need to have 10 different output files of A, one for each m. Please, can you help?

Use sprintf() to build up a unique filename in each iteration that
depends on m or whatever else you want.

folder = 'c:\whatever';
for m = 1:10
% Your matrix code......

% Create filename.
baseFileName = sprintf('File %d', m);
fullFileName = fullfile(folder, baseFileName);

% Open file for writing.
fid = fopen(fullFileName , 'wt');

% Write out A or Y or whatever you want with fprintf()
% fprintf();

% Close this file.
fclose(fid);
end

From FAQ 4.12 (again)...

datFiles = dir('tot_r2*.dat');
for m = 1:length(datFiles)
fname = datFiles(m).name;
C{m} = load(fname);
...
[p,name,ext] = fileparts(fname);
save fullname(p [name '_A' ext]) A
end

Remember in this case to use the _function_ form of SAVE, not the _command_
form.

save( fullname(p, [name '_A' ext]), 'A')

not

> save fullname(p [name '_A' ext]) A
