MATLAB: How to change integer format

double

how to make the double value format… like 02 instead of 2 ?

fprintf('%0.2d\n',2)
02
fprintf('%0.2d\n',3)
03
fprintf('%0.4d\n',3)
0003

No loop needed

nu = 1 : max_nu;
roll=-0.01-0.002*nu;
pitch=0.01+0.002*nu;
yawn=0.005+0.002*nu;
Wx=0.0002+0.0001*nu;
Wy=0.0003+0.0001*nu;
Wz=0.0004+0.0001*nu;

[fid,msg] = fopen('name.csv','wt');
assert(fid>=3,msg)
fprintf(fid,'{%.3f,%.3f},\n',A.');
fclose(fid);

The file it produces is attached, and looks like this:

{0.000,1.000},
{1.000,2.000},
{2.000,3.000},
