Details:

When I use `optimset` with displaying iteration parameter as option for
`fzero`, it doesn't show any iteration at all.

Attached are the .m file and the screenshot of the command window. I have
tried these alternatives:

- Defining f in a separate file
- Writing on the command instead of the file
- Defining f and optimset directly within fzero
- Not assigning fzero to any variable
- Assigning fzero to all four variables

My friend who uses MATLAB write the same code and it worked - it shows the
table as it should (attached file).
