Variables are stored but not shown is the workspace?

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.

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.

The variable name "ans" is reserved by MATLAB.

type "doc ans" to read it

[Yalc Copper]

it is not about ans or other variable names. I tried other names, and the variable just cannot show in the workspace

[Fangjun Jiang]

Try the following in MATLAB Command Window

a=1;
b=2;
workspace
open a
