MATLAB: How to use dlmwrite in a for loop

Question

Hi everybody, I want to use dlmwrite to save data in .dat format for a cell array in the workspace.

Thats what I want obtain:

dlmwrite('Ejex1.dat', Ejex{1,1}','delimiter','\t','precision',16)
dlmwrite('Ejex2.dat', Ejex{1,2}','delimiter','\t','precision',16)
dlmwrite('Ejey1.dat', Ejey{1,1},'delimiter','\t','precision',16)
dlmwrite('Ejey2.dat', Ejey{1,2}','delimiter','\t','precision',16)

But the problem is when I try to put in a for loop, I tried many ways to obtain that but it doesn't work well:

for i=1:numfiles
    NameFile(i)=filename(i)
    dlmwrite('NameFile%d.dat',Ejex{1,i},'delimiter','\t','precision',16)
end

Another:

for i=1:numfiles
      NameFile(i)=filename(i)
      dlmwrite(NameFile.dat, Ejex{1,i},'delimiter','\t','precision',16)
  end

Thanks in advance!! I hope you can help me

matlab is not going to fill in the %d number for you. you should be using something like sprintf to a variable to generate the filename for dlmwrite.

 for i = 1:size(Ejex,1)
    Xfilename = sprintf('Ejex%d.dat',i);
    disp(Xfilename)%use xfilename for your dlmwrite  
 end
