"format short" or "format long". See also your Preferences -> Command Window Preferences, as the default can be set there.

format shortg or format longg is better at getting rid of the scientific notation.

[Raghavendra Reddy P]

Thank you "format shortg" done the trick. just a small doubt, how did i have to know that which format right now am working on.

I have the same issue but the above answers are missing some bits. Solution is clear but how to apply "format long g" to the project ? Should I run the simulation again or it converts the variables in the workspace immediately, i.e as soon as I prompt it in the command window ? I've tried a couple of steps but none of them seem to work...

[Stephen23]

@Maximilian Arpaio: the format is a property of the command window. It affects how numeric values are displayed in the command window. You can set the format and then after that all numbers will be displayed using the format that you selected, until you change it again. The format is not a property of projects or functions (although it might be set by them).

Thank you so much for giveing these command, this is very useful, when other operations are applied on these numbers.

Use

format shortG
>> 1.0e+03
ans =
      1000

Far out, thank you my man! It's seriously irritating enough then I tend to use symbolab instead of matlab

How avoid exponnetial number in my matlab gui interface:

[Walter Roberson]

If you are looking at the variable browser, then you can use Preferences -> Variables -> Default array format to change to a different format for the variable browser. For values that are being output by disp() or implied disp() to the command window then Preferences -> Command Window -> Text Display -> Numeric Format sets the "format" command that is done for you when you start MATLAB.

If you are talking about numeric data that is entered into a uitable(), then the only control you have is to set the ColumnFormat property for the column to one of the format types such as 'longg' . However you cannot use a standard format specification such as %0.7f . If you need that level of control, then best is to sprintf() or sprintfc() or compose() to convert the numbers to character vectors or string objects and set that into the uitable.

If you are talking about numeric data that you are setting as a String property of a uicontrol listbox or popup, then use sprintf() or sprintfc() or compose() to format it before setting it as the String property.

Hi my script is this

n=[1.5,3.4;91250,73000]

but it comes out as

n =

1.0e+04 *

0.0001 0.0003

9.1250 7.3000

the 1.0e+04 * automatically comes out of nowhere and disturbs my data all the time. Anyone knows why?

[Walter Roberson]

for the reasons discussed above. Give the command

format long g

and display the data again
