prompt = 'Enter atleast 10 numbers: ';
str=0;
str = input(prompt,'s');
while length(str)~=10
str = input(prompt,'s');
end
that is the code that I'm using right now but I want the user to be able to input as many characters as they want but they can only enter 10 numbers. For example the user should be able to input:123we45ru687u90 but as long as it has ten numbers, the code will continue, no matter the amount of characters. Thank you!

You remove the while condition. Simply use
prompt = 'Enter atleast 10 numbers: ';
str = input(prompt,'s');

If they must enter exactly 10 numbers and any number of characters, I would change your code to
prompt = 'Enter at least 10 numbers: ';
str='0';
while length(regexp(str,'\d'))~=10
str = input(prompt,'s');
end
