matlab连接字符串

str1 = 'nice'

str2 = 'to'

str3 = 'meet'

str4 = 'you'

方法一：

ret = [str1, str2, str3, str4]

结果为'nicetomeetyou'

方法二：

ret = strcat(str1, str2, str3, str4)

结果为'nicetomeetyou'

如果ret = strcat([str1, str2], [str3, str4])

结果为'niceto'  'meetyou'

如果ret = strcat({str1, str2}, {str3, str4})

结果为nicetomeetyou

方法三：

ret = sprintf('%s%s%s%s', str1, str2, str3, str4)

结果为'nicetomeetyou'

还可以和数字一起

num=2016

ret = sprintf('%s%s%s%s%d', str1, str2, str3, str4, num)

结果为'nicetomeetyou2016'
