How can I use fprintf to print values with the same length (the number of digits after the pointer is changing based on the number of digits before the pointer)?
0.00000000
30.0000248
360.000305

b=360.000305
m=9 % fixed length
out=sprintf('%9.9f',b)
ii=numel(strfind(out,'.'))
out=out(1:m+ii)

Please add the following line (for the sake of completeness). I will accept the answer. Thanks for your great help.
fprintf('%s\n', out);

% Azzi's got no time for correctness
fprintf('%s\n', out)
