When I apply the command: format short , my numbers only arrive as 5 digit strings.

When I apply the command:format long, my numbers arrive as massive 14 digit strings.

I want to be able to customize this. Ideally I should be able to do something like:

short=8 , and then: format short, would make my numbers have 8 digits instead of 5.

Is there a way to do this in matlab?

No, there is no way to do that in Matlab, as the premise is incorrect. The 'format'
command affects only the display of values via disp() or by default output
(no semi-colon after an expression), and in no way affects the number of digits
that "arrive", and in no way affects the number of digits that are saved in .mat
files or that are saved via save -ascii, and in no way affects csvwrite() or
dlmwrite().

If your request is to change the format used by disp() or by default output,
to something not already supported by the 'format' command, then NO, there is
no way to do that.

That response did not help -us- to know what was not acceptable about using sprintf()
in your situation.

Well, that's not quite true -- you can overload disp and display to do
whatever you want.
