if ischar(tline)是判断tline变量是否是字符串类型的变量，而break是跳出最近的一层循环，控制程序执行包含break的最内层循环后的第一条语句。而end是MATLAB中for循环，while循环，if条件语句的结束标志，类似于其他语言(如C/C++)中的花括号之类的。不知道我又没有回答到你的问题。这是一个条件语句啊...

For instance, if A is a string, "foo", c is a character array, 'foo'. example C = char(A1,...,An) converts the arrays A1,...,An into a single character array. After conversion to characters, the input arrays become rows in C. The char function pads rows with blank spaces as...
