Converting user input char to an array

As part of my university matlab module i was assigned to do an assigment from one of 4 options. I'm on a bit of a road block, part of code is requesting the user to type in 6 numbers for a lottery game, being that this data is recorded as a char i want to convert this to a numerial array (matrix). I have tried the following with no luck.
player_numbers = input ('Please enter your number: ','s');
player_lotto_numbers = str2num(player_numbers);

That code should work for a variety of input formats, including if the user puts spaces or commas between the numbers. What problem are you encountering?
It comes back with the following error "undefined function 'str2sum' for input arguments of type 'char'". I have search everywhere for an answer but I have found nothing

It‘s not st2sum it’s str2num(). Usually str2double() is preferred.

Also if 's' is removed from input() the input is assumed as a double array but to be kept in mind that the input is a valid input for instance
[1,4,6]
As the user is entering multiple numbers, str2double() would not handle the situation directly.
"It‘s not st2sum it’s strnum()"
Actually its str2num, although str2double is generally preferred.
It is often possible to use sscanf for multiple numbers in an vector.
Thank you Stephen indeed it’s str2num() it was a typo.
I'm a bit of a novice, soo how would I approach this problem. Would stake the 's' solve the problem I'm having?
What you posted is str2num(), which is valid.
But your error message was about str2sum() with a 'sum' instead of a 'num' . That does not exist.
The code you had posted was right.
