How can I use fprintf to print in scientific format, always starting with 0.XXXXXXE-0Y in case of a positive number, or -.XXXXXXE-0Y in the case of a negative number.
Example: a=-0.07639297; fprintf('%E',a);
This will print the number as: -7.639297E-02
However, I want to have it as: -.7639297E-01
Thanks!

You have to ‘adjust’ the format a bit, but it can be done as a string:
a=-0.07639297;
expstr = @(x) [x*10.^floor(-log10(abs(x))) floor(log10(abs(x))+1)];
Result = sprintf('%.7fE%+04d', expstr(a))
Result =
-0.7639297E-001
Tweak the format in the sprintf call to your liking.
