matlab从入门到精通第13章书后源码对初学者很有帮助

% 创建InetAddress对象
function resolveip(input)
try 
 address = java.net.InetAddress.getByName(input);
catch 
 error(sprintf('Unknown host %s.', input));
end
% 获取域名或IP
hostname = char(address.getHostName);
ipaddress = char(address.getHostAddress);
% 显示域名或IP
if strcmp(input,ipaddress)
 disp(sprintf('Host name of %s is %s', input, hostname)); 
else 
 disp(sprintf('IP address of %s is %s', input, ipaddress));
end
