convert string to number array in matlab

Question

I have a script in which a string of number is entered

string='123'

or

string='9823'

I am trying to convert this into an array of the form [a,b,c,d] e.g from a string of '123' to a numerical array [1,2,3]

Any tips on how to do this?

Answer 1

str = '123';
num = str - '0';
% num = [1 2 3];
