Question
Which temporary variable does MATLAB use to store the most recent answer?
Multiple Choice
pii
, j
, NaN
, ans
Solution
The temporary variable that MATLAB uses to store the most recent answer is ans
. When you perform a calculation in MATLAB without explicitly assigning it to a variable, the result is stored in the default variable ans
. This allows you to immediately use the result of a computation in subsequent operations without needing to assign it to a named variable.
Explanation:
In MATLAB, every calculation or expression you evaluate results in a value being stored in ans
if you do not provide a variable name. For example, if you type 5 + 3
, MATLAB will calculate the result 8
and store it in ans
. You can then use ans
in further calculations, such as typing ans * 2
, which would yield 16
. This feature is particularly useful for quick calculations where defining a variable is not necessary.
Final Answer
The correct answer is ans.
