I type in ans=1 in command window and I can recall it and also can find it in the control tab. But the variable just does not appear in the workspace. I reviewed some questions but all of them are about functions or scripts. Please help me.

在 MATLAB Online 中打开

clear
x = 1;
ans = x+1
ans = 2
whos
  Name      Size            Bytes  Class     Attributes

  ans       1x1                 8  double              
  x         1x1                 8  double              

As you can see, the variable ans does appear. HOWEVER, you should never be using ans as a variable! It is a reserved name, a variable name that will be overwritten frequently, and not under your control.

Even on my own computer, ans does show up in the workspace pane. So I am not sure what exactly you did. If you have some behavior that is confusing you, then you need to be more clear about it.
