Hello,
I want to make a typo refund if there is a user error with negative. For example if a user types negative then the output will return the same as original.
Thanks for the helpers
clc;
clear;
v=input('Insert poisson ratio:'); %Poisson's ratio
if isempty(v) || (v<=0)
end

while true
v = input('Insert poisson ratio: '); %Poisson's ratio
if isnumeric(v) && isscalar(v) && v >= 0
break
end
end
