Hi everyone, I am new to MATLAB, and I have a question on how to restrict inputs on Matlab. I want to make sure you that my input is exactly a 5 digit number, and it cannot be alphabets.
Thank you

Assuming "5 digits" means an integer (positive or negative)
% Function to test x
testx = @(x)isnumeric(x) && ... % x must be a number
isscalar(x) && ... % x must be scalar
mod(x,1)==0 && ... % x must be an integer
abs(x)<100000 && abs(x)>9999; % x must have 5 digits (pos or neg)
% Some tests
testx(12345)
testx(-12345)
testx('a')
testx(3.1213)
testx(00001)
testx(99999)
testx([12345 54321])
