how to save result from nested for loop?. i am totally confused sir,please send some material to understand about saving result.

"Put z inthe first column" is not an exact definition of the output. Do you want to write an ASCII file?

FID = fopen(FileName, 'w');
if FID < 0, error(Cannot open file); end
data = [z, y, x];
fprintf(FID, '%g %g %g\n', transpose(data));
fclose(FID);

See "help fprintf", if you want to specify another numerical format, e.g. more digits after the dot.

Hi,

what you like to do can be done with eval:

n = 5;
for k = 1:1:n;
      eval(['array_',num2str(k),'= k^2+2*k;']); % Just an example
end

But I would recommend avoid eval and use a Cell instead to capture the output:

n = 5;
array = cell(n,1);
for k = 1:1:n;
      array{k} = k^2+2*k;
end

For some more details look under the following link for "How can I create variables A1, A2,...,A10 in a loop?"
