Hi Im using fgets to display every line in the file.

fid = fopen('file');

tline = fgets(fid);

while ischar(tline)

    L = (tline);
    tline = fgets(fid);
    disp(tline)    

end

I would like to save every line in the workspace in sequence as L1, L2, L3 ...

Can You propose me a solution?

Thank You.

Thanks, but yes I know this possibility. most important for me is have to save every line separately in workspace, becouse I work with several files and I dont know how leinght it is, and I can't appeal directly to line becouse it could not exist.

fid = fopen('file');
line1 = fgetl(fid);
res=line1;
k=0
while ischar(line1)
  k=k+1;
  line1 = fgetl(fid);
  assignin('base',sprintf('L%d',k),line1)
end
fclose(fid);
