Hi
I am doing
Out2 = regexp(TL5{3},'\w*','match');
where
>> TL5{3}
ans =
'3000,3e-12'
which returns me
Out2 =

'3000' '3e' '12'

In regular expressions: \w --> Any alphabetic, numeric, or underscore character. For English character sets, this is equivalent to [a-zA-Z_0-9].

Modify \w into '[a-zA-Z-0-9]*' to include "-".

You would need to use [-a-zA-Z_0-9] to extend to include "-". "-" is
magic in where it has to go because of its role in indicating a range.

Also, [a-zA-Z_0-9] is not exactly the same as \w because \w includes
alphabetic characters according to the current character set setting.

I would suggest that instead of using '\w*' and 'match', that the OP
consider using ',' and 'split'

Yes, definitely more readable:
Out = regexp(TL5{3}, ',' , 'split');
