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.
