I need to get the correct input from the user, when the user enters the wrong input, it display an error for the while material line. Not sure what im doing wrong here.
material = input('Please enter Uranium, Vanadium, Zinc, or Zirconium: ', 's');
while material ~= 'Uranium' && material ~= 'uranium' && material ~= 'Vanadium' && material ~= 'vanadium' && material ~= 'Zinc' && material ~= 'zinc' && material ~= 'Zirconium' && material ~= 'zirconium'
material = input('ERROR! Please enter Uranium, Vanadium, Zinc, or Zirconium: ', 's');
end

Use this string comparison command instead of simple comparison in your IF condition: strncmpi(material, 'uran', 4) || strncmpi(material, 'Uran', 4) || strncmpi(material, 'Zinc', 4) ....
