Extended data:
Input and output of matlab
The output statement is a very simple disp ('Yes, of course')?
In this case, of course, you can output yes.
If you want to output a variable, just output the variable name to disp (variable name).
About input:?
There is nothing to say about input, just input.
For example: enter ('Please enter an integer')?
In this case, it will output a sentence: Please enter an integer, and then you can enter a numerical value?
At the same time, it should be said that input also has a return value, which can return two types: number or string. number has defaulted, and string has no default, so it needs to be declared by itself. Like what?
X = input ('Yes, of course'); Can you return a number?
X = input ('Please enter a string',' s'); Returns a string
The specific operation in Matlab is given.
Input ("such an instance");
X = input ('Please enter an integer');
X = input ('Please enter a string',' s');
Disp ('invincible in Chinese');
disp(x)；
