Matlab, how to convert a string of integers into a vector? [duplicate]

Answer 1

one way would be using regexp for this. But of course it only works for single digit numbers.

>> str = '123456789';
>> num = regexp(str,'\d')

num =

 1     2     3     4     5     6     7     8     9

Answer 2

If all you have is contiguous characters from 0 to 9:

v = double(s)-'0';

double(s) converts a string into an array where each element is the ASCII code of the corresponding character. To obtain the numberic values we subtract '0' (which is in fact 48 in ASCII) and since digits have a sequential representation in ASCII code ('1' = 49, '2' = 50, etc.) we end up with intended result.
