虽说是讲述字符(char)与字符串(string)的相关操作,但相较于 字符串(string)来说,字符(char)的使用更多,所以这里说字符(char)更多些。 1. 字符串的长度 常用的检测字符串长度的函数有两个 —— length()...
使用MATLAB 时,可发出创建变量和调用函数的命令。例如,通过在命令行中键入以下语句来创建名为 a 的变量: a = 1 MATLAB 将变量 a 添加到工作区,并在命令行窗口中显示结果。 创建更多变量。 b = 2 c = a + b d = cos(a) 如果未指定输出变量,MATLAB 将使用变量 ans(answer的缩略形式)来存储计算结果。
