I have a data array that has this format. >> whos DATA_matrix Name Size Bytes Class Attributes

DATA_matrix 756806x8 48435584 double

I am trying to loop thru the first 10 rows of data and display it like it shows up in the variable window.

for i = 1:10

    for j = 1:8
       sprintf('%8f',DATA_matrix(i,j)) 
    end
end

When I run this code it prints out like

ans =

0.000000

ans =

27.000000

How do I get it to pint out each row on a separate line?

for i = 1:10
  for j = 1:8
     fprintf('%8f  ', DATA_matrix(i, j));
  end
  fprintf('\n');
end

It is faster and simpler to call FPRINTF with a vector:

for i = 1:10
  fprintf('%8f  ', DATA_matrix(i, 1:8));
  fprintf('\n');
end
