mass = input('What is the mass of %s (kg)? ', a)

radius = input('What is the estimated radius of %s (km)? ', a)

masssp = input('What is the mass of the specimen (kg) ')

newton = (mass * radius)/masssp

fprintf('On %s , it would weight approxomately %d Newtons ', s, newton)

【解决方案1】：

你的文本需要 sprintf

a = input('What is the name of the exoplanet? ','s');
mass   = str2num(input(sprintf('What is the mass of %s (kg)?', a),'s'));
radius = str2num(input(sprintf('What is the estimated radius of %s (km)?', a),'s')) ;

然后将你的字符串转换为数字，否则你不能用它进行计算......
