your_answer = strfind(num2str(1050),num2str(5));

locationOf5 = strfind('1050', '5')

You can adapt it to other numbers, or pass in string variables instead of hard-coding it if you want.


Thanks Image Analyst !! What would be the code if the input is not a string?

see answer by Jose-Luis

locationOfDigit = strfind(num2str(yourFullNumber), num2str(yourDesiredDigit))
