Hi, I have a cell (Numbers) with different values and I have a vector with the positions I want to take (NumbersSelect) When I write a=Numbers{NumbersSelect} I only get in the variable a the first number I want to select I have developed a for loop in order to take all the numbers there is a way to do it without a for loop ??? thanks

If you have spaces in your original string, first use a regexp call to create a cell array of strings from the individual words:
str = 'I have a string';
strc = regexp(str, '\ ', 'split')
strc =
1×4 cell array
'I' 'have' 'a' 'string'
That should work with Adam’s code. If you have something else that wouldn’t work with this approach, you need to share it with us.

Perhaps you mean:
a = Numbers(NumbersSelect)
or
a = sprintf('%s ', Numbers{NumbersSelect})
If this does not help, please post some real example data and the wanted output in valid Matlab syntax.
