Hi,

The input to the function "timeit" should be a function handle as mentioned in the documentation - https://www.mathworks.com/help/matlab/ref/timeit.html#btx36ta-f:~:text=Function%20to%20be%20measured%2C%20specified%20as%20a%20function%20handle.%20f%20is%20either%20a%20handle%20to%20a%20function%20that%20takes%20no%20input%2C%20or%20a%20handle%20to%20an%20anonymous%20function%20with%20an%20empty%20argument%20list.

For an example that demonstrates the usage of the "timeit" function to measure code performance, refer to this link - https://www.mathworks.com/help/matlab/ref/timeit.html#d126e1852968:~:text=Compare%20Time%20to%20Execute%20Custom%20Preallocation%20to%20Calling%20zeros.

Hope this helps!
