In MATLAB, you can extract specific digits from a number by converting it to a string and then indexing into that string. For example, to extract the third digit of a number num, you can use the following code:

numStr = num2str(num); % Convert the number to a string
digit = numStr(3); % Access the third character

Alternatively, if the number is an integer, you can also use modulus and division operations to isolate specific digits.
