Are the '[' and ']' in the string? Are the numbers only integers or possibly floating point ?

Hi,
as long there are no [] in the string use textscan:
textscan('1 2 3 4 6.3','%f','delimiter',' ')
In the case there are use strrep to remove the [ or ] before calling textscan.

You have
t(i,n+1)=num2str(c);
the destination t(i,n+1) is a single character. The number 10 and upwards require two (or more) characters to represent as a string. Therefore if c reached 10 (occurrences) the code would fail. This suggests that you have a code design problem.
