I would like to print a number with the following format:
.0000000E+00
MATLAB prefers the following:
0.0000000E+000
Is there a way to solve this issue?

This is helpful removing the leading zero. Is there a way to maintain the exponential format? I think i can take care of the E+000 to E+00 issue by simply using some string modification functions.

Perhaps something like this:
char(java.text.DecimalFormat('#,##0.###E00').format(0.1));

fprintf('%1.5s',0.1)
1.5 stands for 5 decimal places.1 is for full number.

you could easily find a way to this problem if you were a c proogrammer...

@Pourya: And obviously your assumption is not really wrong. Thanks for this interesting new piece of information.
Of course TMW did not implement fprintf from scratch but relies on existing libraries. Therefore even known bugs like buffer overflows and other undocumented features like %s with numbers appear in Matlab.
