If a user inputs a random amount of characters For example: str=input(prompt,'s'); and they input: 123wd57ab934bd3 how can I separate the numbers and the characters? Thank you!

str = '123wd57ab934bd3';
z = regexp(str,'(\d*)([a-z]*)','tokens');
out = [z{:}];
out = out(~cellfun(@isempty,out));

is there any way that I could pull out the numbers? maybe even one by one? so instead of separating I get only the numbers.

str = '123wd57ab934bd3';
z = str2double(regexp(str,'\d*','match'));
