Please, I have a small questions.
I want to write numeric data to a file, but the problem is
that I want the numbers to be written at specific places as
in the following example:
$# nid x y
1 0.000 0.02500000
254 -0.02377641 -0.00772543
So, as you can see the numbers should be right aligned under
each of the letters.
Use a format of '%8d%16.8f%20.8f\n'
S = '$# nid x y';
V = [1 0 0.025;254 -0.02377641 -0.00772543];
disp(sprintf('%s',S));
$# nid x yis no
1 0.00000000 0.02500000
254 -0.02377641 -0.00772543
I do note that the first x value is not in the format you
requested (not three digits after the decimal), but there
single format element that expresses "Use at least 3decimal places
but no more than 8". If it is important that there be the3 decimal
places in one case but 8 in the other, then you willeither have to
concatenate together pre-formatted strings, or else useawkward
constructs such as,disp(sprintf('%8d%16.*f%20.8f\n',V(1,1),3,V(1,2),V(1,3),V(2,1),8,V(2,2),V(2,3)))
disp(sprintf('%s',S));
disp(sprintf('%8d%16.*f%20.8f\n',T{:}))
or, more compactly and generalizably,
T = num2cell([V(:,1),[3 8]',V(:,2:end)])';
disp(sprintf('%s',S));
$# nid x yuser-required number of
1 0.000 0.02500000
254 -0.02377641 -0.00772543
The [3 8] in the T line is the insertion of the
decimal places for the element that will follow in the list.the throne of

Thank you very much,
