MATLAB的输入与输出

1.MATLAB的输入语句input函数用于接收用户的输入:

a.输入数据

1 2 3 4

>> x=input('please input a number:') please input a number:22 x =    22

b.输入字符串

1 2 3 4

>> x=input('please input a string:','s') please input a string:this is a string x = this is a string

2.MATLAB输出语句包括自由格式(disp)和格式化输出(fprintf)两种

1 2 3 4 5 6 7 8 9 10 11 12

>> disp(23+454-29*4)    361 >> disp([11 22 33;44 55 66;77 88 99])    11   22    33    44   55    66    77   88   99 >> disp('this is a string') this is a string >> area=12.56637889; >> fprintf('The area is %8.5f\n',area) The area is 12.56638 >>
