MATLAB: Format of exponential with num2str

exponential format

Hello everybody,
I have a problem and I need some help.
I have something like this :
num2str(2.55, '1.3e') and this gives me
2.550e+000
With 1 for the field width and 3 for the precision after the decimal point.
What I want is this :
2.550+e00
Only 2 zeros for the exponential. Is there a way to do this?
Thank you.

The exponential format differs between MS Windows and the other operating systems.
You can use one of the other operating systems. Or, you can manipulate the returned strings to delete the extra 0. There is no format item to control the number of digits in the exponential.
