Even if my parameters in the command window are displayed with the short format, which I have set from the preferences, when I copy-paste parameters from the workspace they are not in short format. For example, if I have X = 17.2 in the command window, when I copy-paste from the workspace I have 17.2000000000000. I want to eliminate the extra zeros, is there a way to do it?
Thanks

Ran in:
You can use the sprintf function or the num2str function to achieve this.
Example
X = 17.2;
formattedX = sprintf('%.1f', X);
disp(formattedX);
17.2

Thanks for the reply. I actually have a longer array and the command you told me gives "'17.217.217.219.222.022.019.217.219.220.022.019.2'". I want it to be "17.2 17.2 17.2 19.2 22 22 19.2 17.2 19.2 20 22 19.2",
but when I copy-paste the parameter I get "17.2000000000000 17.2000000000000 17.2000000000000 19.1999999999999 22 22 19.1999999999999 17.2000000000000 19.1999999999999 20 22 19.1999999999999"
I hope my comment helps to understand my issue.

Without using fprintf(), you can get rid of some of them by putting this in your script at the top.
format short g

Hi Thanks for the response. I am sorry but I think I am not explaining myself correctly, so I am posting a creenshot. I am already "format shortG" and the values are correctly shown in the command window. My problem is that when I click on the variable under "workshop", it opens it with many digit after the dot (as seen from the right side where it displays "17.199999999999957". So when I copy-paste the variable from the workshop I get "17.199999999999957" even though the same value is 17.2 in the command window. Hope this explaination might help to explain my issue.
Thanks again,
Paris
