calculation by accident. Finally, we observe that the Workspace browser pre-
sents a graphical alternative to whos. You can activate it by clicking on the
Workspace tab, by typing workspace at the command prompt, or through
the View item on the menu bar. Figure 2-2 depicts a Desktop in which the
Command Window and the Workspace browser contain the same information

Errors in Input
If you make an error in an input line, MATLAB will beep and print an error
message. For example, here’s what happens when you try to evaluate 3uˆ2:
>> 3uˆ2
??? 3u^2
|
Error: Missing operator, comma, or semicolon.
The error is a missing multiplication operator *. The correct input would be
3*uˆ2. Note that MATLAB places a marker (a vertical line segment) at the
place where it thinks the error might be; however, the actual error may have
occurred earlier or later in the expression.
