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.

Thanks for the answer. Yeah I'm on Windows and I only have this operating system.
How can I manipulate the returned strings to remove the extra zero, knowing that it would be the first zero of the three for the exponential?

I think i'll just manipulate the returned strings. Thanks for the help.
