using fprintf to print same length values
显示 更早的评论
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

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

Never mind. I figured it out and corrected it:
b=[0.00000000
30.0000248
360.000305
12345.678]
m=9; % fixed length
for k = 1 : length(b)
out=sprintf('%9.9f',b(k));
ii=numel(strfind(out,'.'));
out=out(1:m+ii);
fprintf('%s\n', out);
end
Nice clever solution.

Ronaldo, Analyst has corrected the answer, in my answer a should be out. Look at edited answer

This works fine, what is the problem?

Ronaldo, I am not adding anything.
b=360.000305
m=9 % fixed length
out=sprintf('%9.9f',b)
ii=numel(strfind(out,'.'))
out=out(1:m+ii)
% Azzi's got no time for correctness
fprintf('%s\n', out)
