MATLAB: Please how do i make this while statement check all non-positive integers in the vector x below

#vectorconditioning#whilestatements

x = input ('Please input range of values for x: ');
while x <= 0
    disp('One or more inputted data is not a positive integer')
    x = input ('Please re-input range of values for x: ');
end

Best Answer

This checks for any non-positive values:

while any(x <= 0)

Did you also want to check to see if they are integers? E.g.,

while any(x <= 0) | any(floor(x) ~= x)

function s = sfactorial(x)
  if x < 0
      error('x must be positive')
  elseif floor(x) ~= x
      error('x must be an integer')
  else
      result=ones(1,numel(x));
      for k = 1:numel(x)
        for i = 1:x(k)
            result(k) = result(k)*i
        end
      end
  end
  s = result;
end

You don't need two loops,

n = 0;
x=input('enter correct number of k');
while n<3
    n=numel(x);
    if n>=3 && all(x>0)
        break;
    elseif n>=3 && any(x<0)
        x = input('please enter positive values');
        n = 0;
        continue;
    else
        x=input('enter correct number of k');
        n = 0;
        continue;
    end
end
